Security footage circulating on social media shows a man leaving a residential building and walking toward a parking lot. Another man approaches him and fires several shots before running away. An official said that the victim was a colonel in the Security Service of Ukraine (SBU).

Hundreds of Russian drones and more than a dozen missiles rained down on the Ukrainian capital early on Thursday, killing two people in a second massive air strike on Ukraine in two days as Kyiv seeks critical aid from its partners at a meeting in Rome.

Kyiv is again under a massive overnight Russian drone attack, local officials say, with at least eight people reported injured and fires burning across the city.

Hours after Pres. Trump railed against Vladimir Putin, saying "he’s very nice all the time, but it turns out to be meaningless," Russia unleashed more than 700 drones into Ukraine.
