Diplomatic efforts to end the war in Ukraine were stepping up on Monday, with Ukrainian and Russian negotiators set to talk again after both sides cited progress, even after Russia attacked a base near the Polish border and fighting raged elsewhere.
A barrage of Russian missiles hit Ukraine's Yavoriv International Center for Peacekeeping and Security, a base just 25 kilometers (15 miles) from the Polish border that has previously hosted NATO military instructors, killing 35 people and wounding 134, a Ukrainian official said Sunday.
Russia's Defense Ministry said the airstrike had destroyed a large amount of weapons supplied by foreign nations that were being stored at the sprawling training facility, and that it had killed "up to 180 foreign mercenaries."
