KYIV, Ukraine (AP) 鈥 After being encircled by Ukrainian forces, Russia pulled troops out Saturday from an eastern Ukrainian city that it had been using as a front-line hub. It was the latest victory for the Ukrainian counteroffensive that has humiliated
Russia鈥檚 withdrawal from Lyman complicates its internationally vilified declaration just a day earlier that it had 鈥 an area that includes Lyman. Taking the city paves the way for Ukrainian troops to potentially push further into land that Moscow now illegally claims as its own.
鈥淭he Ukrainian flag is already in Lyman, Donetsk region. Fighting is still going on there. But there is no trace of any pseudo-referendum there,鈥 Ukrainian President Volodymyr Zelenskyy said in his nightly address Saturday.
He was referring to 鈥渞eferendums鈥 that Russia held at gunpoint in the four regions before annexing them 鈥 Luhansk, Donetsk, Zaporizhzhia and Kherson.
The fighting comes at a . Facing Ukrainian gains on the battlefield 鈥 which he frames as a U.S.-orchestrated effort to destroy Russia 鈥 Putin this week heightened threats of nuclear force and used his most aggressive, anti-Western rhetoric to date.
Russia鈥檚 Defense Ministry claimed to have inflicted damage on Ukrainian forces in battling to hold Lyman, but said outnumbered Russian troops were withdrawn to more favorable positions. Ukrainian forces moved into the city, and Zelenskyy鈥檚 chief of staff posted photos of a Ukrainian flag being hoisted on the town's outskirts.
Lyman had been an important link in the Russian front line for ground communications and logistics. Located 160 kilometers (100 miles) southeast of Kharkiv, Ukraine鈥檚 second-largest city, it's in the Donetsk region near the border with Luhansk, two regions that Russia annexed Friday.
Ukrainian forces have retaken vast swaths of territory in a counteroffensive that started in September. They have pushed Russian forces out of the Kharkiv area and moved east across the Oskil River.
Moscow鈥檚 withdrawal from Lyman prompted immediate criticism from some Russian officials. The leader of Chechnya, Ramzan Kadyrov, blamed the retreat, without evidence, on one Russian general being 鈥渃overed up for by higher-up leaders in the General Staff.鈥 He called for 鈥渕ore drastic measures.鈥
Meanwhile, on the Russian-annexed Crimean Peninsula, the governor of the city of Sevastopol announced an emergency situation at an airfield there. Explosions and huge billows of smoke could be seen by beachgoers in the Russian-held resort. Authorities said a plane rolled off the runway at the Belbek airfield, and said ammunition on board had caught fire.
Russia annexed the Black Sea peninsula of Crimea from Ukraine in 2014 in violation of international law.
Russian bombardment has intensified in recent days as Moscow moved swiftly with its latest annexation and ordered a mass mobilization at home to bolster its forces. The Russian call-up has proven unpopular at home, prompting tens of thousands of Russian men to flee the country.
Zelenskyy and his military have vowed to keep fighting to liberate the regions that Putin claimed to have annexed Friday, and other Russian-occupied areas.
Ukrainian authorities accused Russian forces of targeting two humanitarian convoys in recent days, killing dozens of civilians.
The governor of the Kharkiv region, Oleh Syniehubov, said 24 civilians were killed in an attack this week on a convoy trying to flee the Kupiansk district. He called it 鈥溠乺uelty that can鈥檛 be justified.鈥 He said 13 children and a pregnant woman were among the dead.
鈥淭he Russians fired at civilians almost at point-blank range,鈥 Syniehubov wrote on Telegram.
The Security Service of Ukraine, the secret police force known by the acronym SBU, posted photographs of the attacked convoy. At least one truck appeared to have been blown up, with burned corpses in what remained of its truck bed. Another vehicle at the front of the convoy was torched. Bodies lay on the side of the road or still inside vehicles that were pockmarked with bullet holes.
Russia鈥檚 Defense Ministry said its rockets destroyed Ukrainian military targets in the area but has not commented on accusations that it targeted fleeing civilians. Russian troops have retreated from much of the Kharkiv region but continue to shell the area.
And a Russian strike in the Zaporizhzhia region鈥檚 capital killed 31 people and wounded 88, Ukrainian officials said. The British Defense Ministry said the Russians 鈥渁lmost certainly鈥 struck a humanitarian convoy there with S-300 anti-aircraft missiles. Russian-installed officials in Zaporizhzhia blamed Ukrainian forces but gave no evidence.
In other developments, in an apparent attempt to secure Moscow鈥檚 hold on the newly annexed territory, Russian forces seized the director-general of the , Ihor Murashov, on Friday, according to the Ukrainian state nuclear company Energoatom.
Energoatom said blindfolded him and took him to an undisclosed location.
Russia did not comment on the report. The International Atomic Energy Agency said Russia told it that 鈥渢he director-general of the Zaporizhzhia nuclear power plant was temporarily detained to answer questions.鈥
The Vienna-based IAEA said it 鈥渉as been actively seeking clarifications and hopes for a prompt and satisfactory resolution of this matter.鈥
The power plant has been caught in the crossfire of the war. Ukrainian technicians continued running it after Russian troops seized the power station, and its was shut down in September as a precautionary measure amid ongoing shelling nearby.
In other fighting reported Saturday, four people were killed by Russian shelling Friday in the Donetsk region, governor Pavlo Kyrylenko said. The Russian army struck the southern Ukrainian city of Mykolaiv twice overnight, once with drones and the second time with missiles, according to the regional governor.
Russia now claims sovereignty over 15% of Ukraine in what NATO Secretary-General Jens Stoltenberg called 鈥渢he largest attempted annexation of European territory by force since the Second World War.鈥
Zelenskyy on Friday formally applied for NATO membership, upping the pressure on Western allies to defend Ukraine.
In Washington, President Joe Biden signed a bill that provides another infusion 鈥 more than $12.3 billion 鈥 in military and economic aid linked to the war in Ukraine.
