KYIV, June 6 - Ukraine was under an ongoing Russian ballistic missile and drone attack early Friday that wounded at least three people, officials said.

Multiple explosions were heard in the capital, Kyiv, where falling debris sparked fires across several districts as air defense systems attempted to intercept incoming targets, said Tymur Tkachenko, head of the Kyiv City Administration.

Three people were wounded, local officials said. They urged residents to seek shelter.

"Our air defense crews are doing everything possible. But we must protect one another — stay safe," Tkachenko wrote on Telegram.

Authorities reported damage in several districts, and rescue workers were responding at multiple locations.

In Solomyanskyi district, a fire broke out on the 11th floor of a 16-story residential building. Emergency services evacuated three people from the apartment, and rescue operations were ongoing. Another fire broke out in a metal warehouse.

In northern Chernihiv region, a Shahed drone exploded near an apartment building, shattering windows and doors, according to regional military administration chief Dmytro Bryzhynskyi. He added that explosions from ballistic missiles were also recorded on the outskirts of the city.

The nighttime attack came hours after U.S. President Donald Trump said it might be better to let Ukraine and Russia "fight for a while" before pulling them apart and pursuing peace, in comments that were a remarkable detour from Trump's often-stated appeals to stop the three-year war.

Trump spoke as he met with Germany's new chancellor, who appealed to him as the "key person in the world" who could halt the bloodshed by pressuring Russian President Vladimir Putin.

Trump on Wednesday spoke with Putin by phone, and said that Russia would seek revenge for Ukraine's stunning recent drone attack on Moscow's bomber fleet, adding that the Russian leader was not ready for any "immediate peace."

Kyiv's daring strikes on Russian airfields Sunday destroyed several nuclear-capable aircraft worth billions of dollars, and dominated the third call between the Russian and US presidents since Trump returned to power.

Putin had earlier appeared to rule out a ceasefire or any direct talks with Ukrainian President Volodymyr Zelensky. Turkey has suggested it could host such negotiations and invited Trump too.

"President Putin did say, and very strongly, that he will have to respond to the recent attack on the airfields," Trump said in a post on his Truth Social network, after a call that he said lasted an hour and 15 minutes.

"It was a good conversation, but not a conversation that will lead to immediate Peace." (ap/ez)
