Four people were killed and more than 50 injured in Ukraine after Russia pummeled targets across the country with drones and missiles for a second straight night.

Russia launched large-scale drone and missile strikes on Ukraine's capital and other parts of the country early on Friday, local officials said. At least four people were killed in Kyiv and at least 20 have been injured, the city's mayor Vitaliy Klitschko said.

Russia hit Ukraine with a barrage of missiles and drones days after Kyiv's planned drone attack in Russian territory. The attack comes a day after President Trump voiced frustration on the stalled peace talks between the countries.
