Russia bombarded Ukraine with hundreds of drones and dozens of missiles in a large-scale overnight attack, officials said Friday, killing at least four people. For only the second time, it used a new hypersonic missile it says flies at 10 times the speed of sound and is unstoppable.
Ukraine's security service said it considered the use of the missile a war crime.
Ukrainian President Volodymyr Zelenskyy said on social media that a Russian drone hit the Qatar embassy. He noted that Qatar has played a key role in mediating the exchange of prisoners of war.
The intense barrage and the launching of the nuclear-capable Oreshnik missile came days after Ukraine and its allies reported major progress toward agreeing on how to defend the country from further Moscow aggression if a peace deal is struck to end Russia's almost 4-year-old invasion.
Months of U.S.-led peace efforts have failed to stop the fighting, however. Zelenskyy says he has made significant progress on the terms of a possible peace settlement in talks with Washington envoys. But Moscow has given no public signal it is willing to budge from its demands.
