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 attack on Friday, which killed at least four people nationwide, came two days after Russia vowed retaliation for an audacious drone assault on its strategic bomber bases.

Ukrainian President Volodymyr Zelenskyy said emergency operations were underway across multiple regions to clear debris and rescue victims possibly trapped under rubble.
