President Volodymyr Zelensky held a phone call with U.S. President Trump’s Special Envoys Steve Witkoff and Jared Kushner on Christmas Day to discuss "several substantive details" of ongoing peace talks, the president said.

Ukrainian forces struck multiple targets inside Russia overnight Dec. 24-25, hitting oil refining facility, a port, and a military airfield, the Ukrainian General Staff and a source from the the Security Service of Ukraine (SBU) said.

Ukraine is marking its fourth Christmas under a full-scale Russian invasion.

The missiles struck the refinery, triggering multiple explosions, the General Staff said, adding that the extent of the damage was still being clarified.

Ukrainian intelligence sources said the officers had previously taken part in Russia's war against Ukraine and were implicated in the abuse of Ukrainian prisoners of war (POWs).

Russia launched 131 drones at Ukraine overnight, the Air Force said. Ukrainian air defenses intercepted 106 drones. At least 22 drones made it through, striking 15 locations.

The number includes 860 casualties that Russian forces suffered over the past day.

Russia's Defense Ministry reported that between 1 p.m. and 8 p.m. Moscow time on Dec. 24, its air defense systems intercepted and destroyed 132 Ukrainian drones.

"'May he perish,' each of us may think to ourselves," Zelensky said, referring to Russian President Vladimir Putin. "But when we turn to God, of course, we ask for something greater. We ask for peace for Ukraine."
