President Volodymyr Zelenskiy said on Friday that Ukraine was working on the rapid development of interceptor drones to counter the swarms of Russian drones that have been descending on Ukrainian cities in increasing numbers in recent weeks.

A combined Russian missile and drone attack on Ukraine overnight killed at least 15 people — including an American citizen — and wounded scores of others, according to Ukrainian officials.

Authorities say Russian drones have slammed into two Ukrainian cities, killing at least one person in nighttime attacks
