The Ukrainian Air Force has reported "ballistics on Kyiv," as air defense measures were activated in the capital city.
Kyiv's Mayor Vitaly Klitschko said three people have been injured in the ongoing, overnight attacks. He said in a post on Telegram that Russian drones are "entering the city" and urged people to "stay in shelters."
Of those injured, two were hospitalized and one was treated on the spot, Klitschko said in an update.
The mayor said medics were "heading to the scene" in an earlier post on Telegram after the attacks began.
Metro tracks between two stations in Kyiv were damaged from the attacks, but there was no fire or casualties, the head of the Kyiv City Military Administration Timur Tkachenko said via Telegram.
He wrote in an earlier post that the city is under a "combined attack."
"Our air defense calculations are doing everything possible. But we must protect each other! Stay safe," Tkachenko said.
The Ukrainian Air Force also reported cruise missiles heading towards Lutsk, Chernihiv, Lviv, and the Rivne regions of Ukraine around 4:30 a.m. local Ukrainian time.
Earlier there were preliminary reports that a "high-rise building was hit" in Chernihiv, a city northeast of Kyiv, the head of the Chernihiv City Military Administration Dmitry Bryzhynskyi wrote via Telegram.
"The city is currently under attack," Bryzhynskyi added.
The escalation of attacks between Ukraine and Russia comes as U.S.-brokered peace talks between the countries have failed to come to fruition. High-level delegations from both Ukraine and Russia met in Istanbul, Turkey, on Monday for a second round of talks, but the proposed memorandums presented by each delegation have not moved forward in any meaningful way.
In a phone call between Russian President Vladimir Putin and President Donald Trump on Wednesday, the memorandums for a potential peace deal presented Monday were not discussed, Putin's aide Yuri Ushakov told reporters.
A U.S. official also said this week that there was evidence that Russia was preparing to retaliate against Ukraine for the drone strikes that targeted Russian military sites on Sunday.
At least 11 Russian bomber aircraft and one large transport plane were badly damaged or destroyed in Ukraine's drone attack against Russia, according to satellite imagery reviewed by experts and ABC News.
The covert operation was described as one for the "history books" by Ukraine's President Volodymyr Zelenskyy.
Ukrainian Air Force reports 'ballistics on Kyiv' amid reports of strikes in Chernihiv
乌克兰空军报告了“基辅的弹道”，因为首都的防空措施已经启动。
基辅市长维塔利·克里琴科表示，在持续的夜间袭击中，已有三人受伤。他在Telegram的一篇帖子中说，俄罗斯无人机正在“进入城市”，并敦促人们“呆在避难所”
Klitschko在最新消息中说，受伤者中，两人住院，一人当场接受治疗。
市长说，袭击开始后，医护人员在电报的早期帖子中“前往现场”。
基辅市军事管理局局长帖木儿·特卡琴科通过电报表示，基辅两个车站之间的地铁轨道在袭击中受损，但没有火灾或人员伤亡。
他在早些时候的一篇帖子中写道，这座城市正遭受“联合攻击”
“我们的防空计算正在尽一切可能。但是我们必须互相保护!注意安全，”特卡琴科说。
乌克兰空军还报告称，乌克兰当地时间凌晨4点30分左右，巡航导弹向乌克兰的卢茨克、切尔尼戈夫、利沃夫和罗夫诺州飞去。
此前有初步报道称，基辅东北部城市切尔尼戈夫的一座“高层建筑被击中”，切尔尼戈夫市军事管理负责人Dmitry Bryzhynskyi通过电报写道。
“这座城市目前正在遭受攻击，”Bryzhynskyi补充说。
乌克兰和俄罗斯之间的袭击升级之际，美国斡旋的两国和平谈判未能取得成果。乌克兰和俄罗斯的高级代表团周一在土耳其伊斯坦布尔举行了第二轮会谈，但双方代表团提交的拟议备忘录没有取得任何有意义的进展。
普京的助手尤里·乌沙科夫(Yuri Ushakov)告诉记者，俄罗斯总统弗拉基米尔·普京(Vladimir Putin)和美国总统唐纳德·特朗普(Donald Trump)周三通电话时，没有讨论周一提交的潜在和平协议备忘录。
一名美国官员本周还表示，有证据表明，俄罗斯正准备对乌克兰周日针对俄罗斯军事地点的无人机袭击进行报复。
根据专家和美国广播公司新闻(ABC News)审查的卫星图像，在乌克兰对俄罗斯的无人机袭击中，至少有11架俄罗斯轰炸机和一架大型运输机严重受损或被毁。
乌克兰总统弗拉基米尔·泽连斯基将这次秘密行动描述为“历史书”上的一笔。
