Russia sent waves of drones and missiles in an attack on two Ukrainian cities early Tuesday that killed two people and wounded at least thirteen others, Ukrainian officials said. Ukrainian President Volodymyr Zelenskyy in an online statement called the attack "one of the biggest" in the war that has raged for over three years,

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.

The warring sides also exchanged prisoners in one of the few results of talks last week, and Russia reported new attacks on the front line.
