Four people were killed and at least 13 were injured in Ukraine's second largest city overnight after Russia launched an aerial assault with drones.

Russian forces staged a "massive" drone attack on Sunday on Kharkiv, Ukraine's second-largest city, killing four people and injuring several others, officials said.

Russians carried out a large-scale drone strike on Kharkiv on the evening of November 23. One residential building was reportedly hit, with multiple casualties and injuries confirmed, according to Kharkiv Mayor Ihor Terekhov and Oleh Syniehubov,

From the front-line city of Pokrovsk in eastern Donetsk, to Zaporizhzhia in the south, there is little doubt that Russia is making advances. But, battlefield monitors suggest the picture is not quite so bleak for Ukraine as Trump and Putin suggest.

Russian attacks have killed four people and wounded more than a dozen in Balakliya and Velykyi Burluk in Ukraine’s Kharkiv region. Two people have also been killed and many wounded in the Dnipropetrovsk region.

KYIV, Ukraine — A large Russian drone and missile barrage killed 10 people and injured dozens more in Ukraine overnight, officials said Wednesday, as Ukrainian President Volodymyr Zelenskyy was due in Turkey for talks on finding a settlement that might end Russia’s invasion of his country.

Russia continued its deadly air strikes on Ukrainian cities, killing at least three people in the Kharkiv region overnight, local officials said, while President Volodymyr Zelenskyy prepared for the next stop on his tour of European capitals to shore up support.

U.S. and Ukrainian officials sought to narrow the gaps between them on Monday over a plan to end the war in Ukraine, after agreeing to modify a U.S. proposal that Kyiv and its European allies saw as a Kremlin wish list.
