Russian forces have pummeled Ukraine with drones and other weapons, killing three people and injuring scores of others despite international pressure to accept a ceasefire.

Ukraine has brought home the bodies of 1,212 soldiers killed in the war with Russia, the Kyiv officials responsible for exchanging prisoners of war said on Wednesday. In Moscow, Kremlin aide Vladimir Medinsky said Ukraine for its part had returned 27 bodies of Russian soldiers.

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.
