Ukraine's overnight drone strikes have forced a temporary suspension of flights in all airports serving Moscow and the country's second-largest city St. Petersburg, but caused no damage, Russian officials reported on Tuesday.

Ukrainian officials say two people were killed and thirteen wounded when Russia attacked the country with waves of drones and missiles.

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.
