Russia attacked several Ukrainian regions with Russian ballistic missiles and drones early on Friday , officials said, with Kyiv mayor Vitali Klitschko saying four people were killed and 20 injured in the capital. Multiple explosions were heard in the city and falling debris triggered fires across several districts as air defence systems tried to intercept incoming targets, said the Kyiv city administration’s head, Tymur Tkachenko. Authorities reported damage in several districts and rescue workers were responding at multiple locations. Officials urged residents to seek shelter.

A fire broke out in a 16-story residential building in Kyiv’s Solomyanskyi district and emergency services evacuated three people from the apartment. Rescue operations were continuing. Another fire broke out in a metal warehouse. Tymchenko said the metro tracks between two stations in Kyiv were damaged in the attack but no fire or injuries occurred.

A Shahed drone exploded near an apartment building in northern Ukraine’s Chernihiv region , shattering windows and doors, the regional military administration chief said. Explosions from ballistic missiles were also recorded on the city’s outskirts, Dmytro Bryzhynskyi added.

The attacks came after Russia accused Kyiv of state terrorism over its drone operation striking Russian heavy bomber planes at air bases in Siberia and the far north at the weekend and said it it would respond as and when its military saw fit, as reported by Andrew Roth in Washington and Pjotr Sauer.

US president Donald Trump said that during a call with Vladimir Putin on Wednesday he urged the Russian president to refrain from retaliating but fully expected Moscow to strike back over Ukraine’s weekend assault. The US president said it may be better to let Ukraine and Russia “fight for a while” rather than pursue peace immediately, and that he told Putin the two countries were like “two young children fighting like crazy in a park”.

The German chancellor, Friedrich Merz, urged Trump to increase pressure on Russia , telling the US president at a meeting in the Oval Office that the violence Trump abhorred seeing was a result of Putin’s invasion of Ukraine.

The International Atomic Energy Agency’s team at Zaporizhzhia nuclear plant in Ukraine heard repeated rounds of gunfire that appeared to be aimed at drones reportedly attacking the site’s training centre, the head of the UN’s nuclear safety watchdog said on Thursday. There were no immediate reports of damage to the centre, it said.

North Korean leader Kim Jong-un vowed to “unconditionally support” Russia in the war at a meeting with top Russian security official Sergei Shoigu, Pyongyang state media reported.
