Ukrainian President Volodymyr Zelenskyy has again condemned Russia's alleged use of Iranian drones, saying its use of such weapons from Tehran shows it is "militarily and politically bankrupt."
Drone and missile strikes continue to target Ukraine's energy infrastructure and residential buildings. Zelenskyy said yesterday that 30% of Ukraine's power stations have been taken out by Russian strikes, resulting in blackouts in many cities.

Meanwhile, the new commander of Russian forces in Ukraine has acknowledged that the military situation there is difficult, particularly around the southern Kherson region.
"The situation in the area of the 'Special Military Operation' can be described as tense," Sergei Surovikin told reporters Tuesday, according to Russian state news agency Tass.
Kirill Stremousov, a Russian-installed deputy administrator of the Kherson region, said on Telegram late on Tuesday that "in the very near future, the battle for Kherson will begin."

Iran to address reports that it supplied drones to Russia for use in Ukraine
Iran's permanent representative to the United Nations will brief reporters on reports that Russia used Iranian drones in Ukraine.
Ambassador Amir Saeid Iravani is expected to address Western allegations following a closed-door U.N. Security Council meeting.
"Iran's supply of these specific types of UAVs to Russia is a violation of UN Security Council Resolution 2231 and it is an issue for the UN Security Council," State Department spokesman Vedant Patel said Wednesday.
Iran has previously denied that it has supplied Russia with a fleet of drones for its ongoing war in Ukraine.

Russia resorting to 'new depths of depravity' in Ukraine, UK says
The U.K. slammed Russia's missile strikes this week across Ukrainian cities calling the attacks "new depths of depravity."
"These horrendous attacks on civilians are another terrible example of the increasingly desperate and vindictive decision making from [Russian President Vladimir] Putin and his military leadership," said Ian Stubbs, on behalf of the British delegation to the Organization for Security and Co-operation in Europe, or OSCE.
Stubbs told the international forum that "the horrendous drone attacks" on Monday has strengthened Western allies resolve in supporting Ukraine.
In the past week, Putin has ordered a slew of Russian missile and drone strikes across major Ukrainian cities.

Ukrainian orchestra debuts at Kennedy Center in benefit concert
The New Era Orchestra of Kyiv held a debut benefit concert at The Kennedy Center in Washington, D.C., with all proceeds donated to President Volodymyr Zelenskyy's UNITED24 initiative.
The orchestra scattered in the early days of Russia's invasion of Ukraine and was reunited in Poland before flying to the United States this month.
The group performed Beethoven's "Symphony No. 7 in A Major, Op. 92" followed by "Evening Serenade from Silent Music," by Ukraine's greatest living composer, Valentyn Silvestrov, and the late Ukrainian composer Myroslav Skoryk's "Melody."
Ukrainian Ambassador Oksana Markarova told CNBC about the ongoing counteroffensive and that her mother was no longer living under Russian occupation as Ukrainian forces recently liberated her city.
Markarova opened the concert at the Kennedy Center with a speech hailing Ukraine's armed forces. Each song received a lengthy standing ovation.

Zelenskyy says Ukraine preparing for breakdown of energy systems throughout the country
Ukrainian President Volodymyr Zelenskyy said the government is preparing for a breakdown of energy systems throughout the country.
"We are working to create mobile power points for the critical infrastructure of cities, towns and villages. We are preparing for various scenarios of possible consequences," Zelenskyy said on the Telegram messaging app.
Zelenskyy said that options were discussed during a strategic meeting on security at energy supply facilities. The meeting comes as Kyiv accuses Moscow of purposefully targeting critical infrastructure like energy facilities.
"Ukraine will defend itself. No matter what the enemy plans and does," Zelenskyy said.

Russia says seized Ukrainian lands are under its nuclear protection
Russia said the four Ukrainian regions it illegally annexed last month are now under the protection of its nuclear arsenal.
The statement from the Kremlin came at a moment of acute tension, with both NATO and Russia expected to hold military exercises shortly to test the readiness of their nuclear weapons forces.
Asked by reporters if the regions were under Moscow's nuclear umbrella, Kremlin spokesman Dmitry Peskov said: "All these territories are inalienable parts of the Russian Federation and they are all protected. Their security is provided for at the same level as [it is for] the rest of Russia's territory."
President Vladimir Putin said last month that Moscow was ready to use nuclear weapons if necessary to defend Russia's "territorial integrity." U.S. President Joe Biden said on Oct. 6 that his threat had brought the world closer to "Armageddon" than at any time since the 1962 Cuban Missile Crisis, when many feared a nuclear war might be imminent.

IAEA chief expects to return to Ukraine 'soon' for nuclear plant talks
International Atomic Energy Agency chief Rafael Grossi expects to return to Ukraine "soon," as talks to establish a security protection zone around the Zaporizhzhia nuclear power plant remain ongoing, Reuters reported.
Russia and Ukraine have repeatedly blamed the other for shelling at the site, which has been plagued with power outages in the last few weeks. On Monday, Ukraine's state nuclear energy firm said Russian shelling cut off the plant's external power supply.
"There is a possibility I will return to Ukraine and Russia, it is in fact what we have agreed in principle, at this moment we are continuing the consultations aimed at establishing the protection zone," Grossi told Reuters.
"This implies an interaction where I receive answers and reactions from the two sides and I am looking for new ways to move forward and for that, at some point, probably very soon I will have to return."
Grossi also told Reuters that he believes Russia's nuclear threats are not an immediate possibility, though "nothing can be ruled out."

Explosions reported in capital Kyiv
Ukraine's capital Kyiv appears to be under attack again with residents reporting explosions in various districts, and an ongoing air raid alert warning residents to remain sheltered.
Kyiv's Mayor Vitali Klitschko and the Kyiv City State Administration both posted on Telegram that air defense units had "shot down several Russian missiles over Kyiv. There is no cancellation of the air alarm! Stay in shelters! Air defense continues to work."
Kyiv has been subjected to a series of drone attacks this week with a residential building targeted on Monday and several people killed when the building collapsed.

Putin introduces martial law in four illegally annexed regions
Russian President Vladimir Putin has introduced martial law in the four regions of Ukraine that Moscow illegally annexed last month.
Martial law will be introduced in Donetsk, Luhansk, Kherson and Zaporizhzhia — the four regions in Ukraine that Moscow claimed as Russian territory following sham referendums in September that Ukraine and its allies have condemned as illegal and illegitimate.
The decision, announced as Putin addressed a meeting of the Russian Security Council on Wednesday, will likely mean that the regions' civil administrations will be replaced by military ones.

Russian official insists Kherson is not being surrendered despite evacuation
The Russian-installed deputy governor of the Kherson region has insisted Russia is not surrendering the city of Kherson, despite calling on residents to evacuate immediately.
"We are not going to surrender the city. We will hold our ground to the end. We will not let the Nazis enter the city," Kirill Stremousov said. Russian officials frequently and baselessly refer to Ukrainian forces as "Nazis" in a bid to demonize them.
Civilians in Kherson, which Russia claims to have annexed and which is only partially occupied by its forces, have been told to leave the region as Russian officials expect that a large-scale counteroffensive by Ukrainian forces to retake the region could be about to begin.
Residents on the west bank of the Dnipro river have been told to cross to the opposite side of the water and to travel on from there to Russian territories. Russian-installed officials say up to 60,000 people could evacuate the area over the next six days.
In a further development, the acting governor of the region Vladimir Saldo told the Rossiya-24 TV channel on Wednesday that entry to the Kherson region for civilians will be very limited for seven days due to the turbulent situation.
"Only those who will be given a pass by the commandant's office" will be able to enter the region, Saldo said, according to comments reported by the Tass news agency. "These are those who are engaged in providing, supplying, working in public utilities," he added.

Ukraine says it has shot down 223 Iranian-supplied drones
Ukraine's air force has claimed that it shot down 223 Shahed-136 Iranian drones in the last 36 days.
In a Telegram post, the air force said the first case of the downing of an Iranian-made "Shahed-136" kamikaze drone on the territory of Ukraine took place on Sept. 13. As of Wednesday, 223 UAVs (unmanned aerial vehicles) of this type have been destroyed.
Iran denies supplying Russia with drones while Moscow has insisted it has not bought or deployed Iranian-made drones against Ukraine despite evidence to the contrary.
Nonetheless, drone attacks on energy infrastructure and residential buildings in Uraine have increased in recent weeks. On Monday, Kyiv experienced at least four drone attacks, officials said, posting images of drone debris with fragments showing the label "Geran-2" in Cyrillic, as they have purportedly been rebranded by Russia.
Explosive-carrying drones pose a problem for Ukraine's armed forces as they can fly lower to the ground and are harder to detect using radar systems. Images from Kyiv on Monday showed policemen trying to shoot down drones as they flew over the city.
"Anti-aircraft missile units, fighter aircraft, self-propelled anti-aircraft guns, mobile MANPADS fire groups, anti-aircraft guns, large-caliber machine guns and other weapons are involved in the destruction of Shahed-136 barrage ammunition, which the occupiers label as "Geranium-2," the air force said.

Russia's military leadership starting to unravel, UK says
Major elements of Russia's military leadership are increasingly dysfunctional, according to the U.K.'s Ministry of Defence, which said that, at the tactical level, "there is almost certainly a worsening shortage of capable Russian junior officers to organise and lead newly mobilised reservists."
It cited an incident last week in which a Russian recruit shot dead 11 other Russian soldiers near Belgorod. The ministry noted that eyewitness testimony suggests that the shooting occurred after an officer's abusive comments toward ethnic minority recruits.
"Poor lower-level leadership is likely worsening the low morale and poor unit cohesion in many parts of the Russian force," it noted in an intelligence update on Twitter Wednesday.
"Four of the five generals with direct operational command of elements of the invasion in February 2022 have now been dismissed. Their replacements have so far done little to improve Russia's battlefield performance."
The lack of command continuity will likely be more disruptive than in a Western military because under Russian doctrine the development of plans sits largely with the commander personally, rather than as a collective effort across a broader group, the ministry stated.

Up to 60,000 people to be evacuated from occupied Kherson
Up to 60,000 people are to be evacuated from the partially Russian-occupied region of Kherson in southern Ukraine, according to the Russian-installed administration in the region.
The organized movement of the inhabitants on the right bank of Dnipro river in the Kherson region to the left bank has begun, with ferries being launched to take people from the city of Kherson to Oleshky and Hola Prystan on the opposite side of the Dnipro river.
Temporary accommodation has been set up in these locations. From there, residents can choose to relocate to "new territories, as well as travel to the constituent entities of the Russian Federation."
Russia's acting governor of the Kherson region, Vladimir Saldo, said the plan was to move up to 60,000 residents of the region, and that this would take around six days. Saldo said on his Telegram yesterday that the relocation was due to Ukraine "building up forces for a large-scale offensive."
"The Russian Federation has formed a military group to repel this offensive. The battlefield of this confrontation can be our land, peaceful cities and villages of the Kherson region," he said.
Russia claims, falsely, that Kherson is now Russian territory after annexing the region, and three others, after sham referendums there in September. A vast majority of people in the region "voted" to join the Russian Federation. The votes were widely seen as rigged and illegitimate and the international community refuses to recognize them.

U.S., Britain and France to discuss Iranian drone transfers at U.N. meeting: Reuters
The United States, Britain and France plan to discuss Iran's alleged drone transfers to Russia at a closed-door U.N. Security Council meeting, Reuters reported citing unnamed diplomats.
Iran has also promised to ship more drones and missiles to Russia, Iranian officials told Reuters.
Ukraine invited U.N. experts to investigate drones they claim are of Iranian origin and have been deployed by Russia, on the grounds that this violates U.N. Security Council Resolution 2231, according to a letter seen by Reuters.
Resolution 2231 endorses the Iran nuclear deal. The diplomats told Reuters that the three countries believe the drone transfers to violate the resolution, and will be asking a U.N. official to notify the members about the issue.

Military situation 'tense' in Ukraine, Russian commander says
The new commander of Russian forces in Ukraine has acknowledged that the military situation in the country is difficult, particularly around the southern Kherson region.
"The situation in the area of the 'Special Military Operation' can be described as tense," Sergei Surovikin told reporters Tuesday, according to Russian state news agency Tass.
"Further actions and plans regarding the city of Kherson will depend on the developing military-tactical situation, which is not easy. We will act consciously, in a timely manner, without ruling out difficult decisions."
Russia still describes its invasion of Ukraine as a "special military operation" and says its aim is to "liberate" the Donbas in eastern Ukraine although it claims to have annexed four partially occupied regions — two in the east that make up the Donbas and two regions in the south, Kherson and Zaporizhzhia — a move Ukraine and its international allies have condemned.
There are reports that Ukraine's forces are trying to reclaim Kherson before winter kicks in, with a counteroffensive there continuing. Kirill Stremousov, a Russian-installed deputy administrator of the Kherson region, said on Telegram late on Tuesday that "in the very near future, the battle for Kherson will begin" but denied yesterday that there were any "large-scale offensives."

Kremlin is militarily and politically bankrupt, Zelenskyy says
Ukraine's President Volodymyr Zelenskyy said Russia's use of Iranian drones shows that the Kremlin is "militarily and politically bankrupt."
Zelenskyy said in his nightly address Tuesday evening that more than 10 Ukrainian regions were subject to "Russian terrorist strikes" over the last 24 hours, including the Zhytomyr, Kyiv, Kharkiv and Zaporizhzhia regions.
"Wherever possible we try to speed up reconstruction work. And of course all this is related to our efforts in defending against drones. We have to remember that the mere fact of Russia turning to Iran for such assistance is admission by the Kremlin that it is militarily and politically bankrupt."
He said Russia had spent dozens of years "spending billions of dollars on their military-industrial complex but in the end had to go cap in hand to Tehran. To receive rather simple drones and missiles."
The president said Russia's apparent reliance on such weapons would not help it strategically. "It's just an additional confirmation to the world that Russia is on the trajectory of its defeat," he said.
Russia has denied it is using Iranian drones. When asked directly if Russia had bought drones from Iran, Kremlin spokesperson Dmitry Peskov said on Tuesday, "no, we do not have such information." Iran has denied reports that it provided Russia with drones and plans to sell more weapons to Moscow.
The Pentagon said on Tuesday that it did not have information at the time to corroborate reports that Iran has promised to provide Russia with surface-to-surface missiles, along with more drones.

'We are completely ready,' Pentagon says in response to 'reckless' Russian threats to use nuclear weapons
The U.S. takes Russian president Vladimir Putin's "reckless" comments about the potential use of nuclear weapons seriously and is closely monitoring the situation, the Pentagon said.
"We are completely ready," Pentagon press secretary Air Force Brig. Gen. Pat Ryder said when asked if the U.S. was prepared if Russia decided to use nuclear weapons.
Ryder added that the U.S. had not found cause to change Washington's strategic nuclear posture.
He also reiterated that the U.S. assesses that Putin has not yet decided whether to use nuclear weapons in Ukraine.

30% of Ukraine's power stations destroyed by Russian strikes in roughly a week, Zelenskyy says
A whopping 30% of Ukraine's power stations have been destroyed by Russian strikes in the past eight days, Ukrainian President Volodymyr Zelenskyy said in the wake of fresh Russian attacks on the country's critical energy infrastructure.
This has resulted in widespread blackouts across the country, with three major cities, including Kyiv, experiencing power outages.
"Another kind of Russian terrorist attacks: targeting energy & critical infrastructure," Zelensky wrote in a tweet. "Since Oct 10, 30% of Ukraine's power stations have been destroyed, causing massive blackouts across the country. No space left for negotiations with Putin's regime."
