Air raid sirens wailed in Kyiv and across Ukraine for a second time on Friday as top European Union officials visited the country, Reuters witnesses said.
There were no immediate reports of any Russian air strikes on Kyiv throughout the day.
The first air alert in Kyiv was on Friday morning. The second, hours later, followed a news conference in the capital involving Ukrainian President Volodymyr Zelenskiy, European Commission President Ursula von der Leyen and European Council President Charles Michel.
