Moscow’s drone strikes have grown exponentially thanks in part to a deal with Iran to produce its Shahed drones on Russian soil.

KYIV, Ukraine (AP) — A combined Russian and missile attack in Kyiv overnight Tuesday left at least 20 people wounded, according to Ukrainian officials.

The attack used almost 500 drones and missiles, breaking a record set just days earlier, as Russia tries to overwhelm Ukraine’s air defenses, which shot down most of the weapons.
