Warsaw and Kyiv remain at odds over the wartime killings

Poland commemorated on Saturday thousands of Poles killed by Ukrainian nationalists during the Volhynia massacres of World War II, as renewed disputes over the wartime killings have fuelled a diplomatic spat between Warsaw and Kyiv.

Officials marked the 83rd anniversary of the massacres, after units of the Ukrainian Insurgent Army (UPA) launched a wave of coordinated attacks against Polish civilians in Volhynia, now in northwestern Ukraine, on 11 July 1943.

Polish Prime Minister Donald Tusk announced on Saturday that a monument would be built to commemorate the civilian victims.

“A Wall of Remembrance will be erected in Warsaw, with an eternal flame and the names of every victim who has been found and identified,” he said.
