Russia and Ukraine held a second round of peace talks where they agreed to exchange more prisoners and to return the bodies of 12,000 dead soldiers.

The attacks come days after Trump says Putin had "very strongly" promised response to Ukraine "Spider web" attack.

A nighttime missile and drone attack on Ukraine killed at least four people and injured 20 others in Kyiv, city mayor Vitali Klitschko said Friday, as Russia targeted at least six regions across the country with 407 drones and 44 missiles in one of its largest coordinated attacks of the three-year war.
