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.

It was the deadliest attack on the Ukrainian capital in almost a year, and came as Moscow has intensified air assaults on the city.

Russia has thousands of Shahed-136 strike drones and their variants in service. The enemy is capable of launching up to 500 drones across Ukraine in a single day. This was stated in a response from the Main Intelligence Directorate of the Ministry of Defense of Ukraine to a request by RBC-Ukraine.
