Ukraine received another 1,245 bodies of its soldiers killed in the war with Russia on Monday in the final stage of the repatriation of remains agreed at talks in Istanbul, Ukrainian officials said.

Ukraine alleged Monday that Russia mixed bodies of its own dead soldiers among the Ukrainian military dead that have been returned, and that more than a million Russians have been killed since conflict began.

After Ukraine’s drone strikes on Russian air bases, the two sides talked for about an hour in Istanbul, and a halt to the fighting seems out of reach for now.
