Russia hit Ukraine with massive airstrikes overnight, with nearly 500 drones and missiles fired, according to Ukraine's air force. Meanwhile, Ukraine says it struck an airbase and drone warehouse deep in Russia.

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.
