Russian drone strikes on Kyiv have increased, a Ukrainian official claims.

A senior Ukrainian military officer claimed that on Tuesday, Russia used attack drones built in Iran to launch “another massive air attack” on Kyiv. The chief of the municipal military administration of Kyiv, Serhiy Popko, claimed in a statement that the “drones entered the capital in waves” and “from different directions,” causing the air raid alert to sound for more than three hours.
