According to the fund, the 58-year-old sustained blast injuries near the village of Skvortsovo in Crimea’s Simferopol district.

Kharkiv Oblast Governor Oleh Syniehubov said the strike killed nearly an entire family: a 19-year-old woman, an 11-year-old boy, and a 45-year-old man.

The announcement came hours after U.S. envoys Steve Witkoff and Jared Kushner landed in Moscow for talks with Putin.

The figure includes 1,260 casualties that Russian forces suffered over the past day, according to the General Staff.
