(ODESA, UKRAINE) -- At least eight people were killed in Ukraine in another night of intense Russian drone and missile strikes, according to Ukrainian officials.
Ukraine's air force said in a post to Telegram that Russia launched a total of 322 "air attack vehicles" into the country, among them 315 drones and seven missiles. The air force said 277 drones were shot down or otherwise neutralized, as were seven missiles.
"The majority of the damage was sustained by civilian infrastructure," Kyiv's military administration wrote in a post to Telegram.
Two people were killed and nine others injured in Odesa, local authorities said. Among the buildings hit in the Black Sea coastal city were a maternity hospital and an emergency medical center, officials said.
One person was killed and four people injured in Kyiv, officials said, in what appears to be one of the largest drone attacks on Ukraine's capital to date.
Closer to the front, five people were killed and 19 injured in front-line regions as a result of airbombs, artillery and smaller drone attacks, according to local authorities.
President Volodymyr Zelenskyy said in a post to social media that Kyiv, Odesa, Dnipro and Chernihiv regions were targeted. Russia's bombardment included at least two North Korean-made ballistic missiles, he added.
"Residential buildings and urban infrastructure were damaged," Zelenskyy wrote. "In Odesa, even a maternity hospital became a Russian target. Thirteen people were injured. Tragically, there are fatalities. My condolences to the families."
"It is vital that the response to this and other similar Russian attacks is not silence from the world, but concrete action," Zelenskyy said in his statement.
"Action from America, which has the power to force Russia into peace," he continued. "Action from Europe, which has no alternative but to be strong. Action from others around the world who called for diplomacy and an end to the war -- and whom Russia has ignored. There must be strong pressure for the sake of peace."
Ukraine continued its own drone strike campaign overnight, according to Russia's Defense Ministry. Russian forces downed 103 Ukrainian drones on Monday night and Tuesday morning, the ministry said in a post to Telegram.
Monday night's attacks came 24 hours after Russian forces targeted regions throughout Ukraine with more than 470 attack drones -- one of the largest aerial strikes of the war, according to Ukraine's air force.
Earlier Monday, Russia and Ukraine held the first stage of a prisoner swap following an agreement reached during peace talks in Istanbul, Turkey. The two sides conducted another prisoner swap on Tuesday, Zelenskyy said.
