This picture taken and released by the Ukrainian presidential press-service on July 8, 2018 shows Ukrainian leader Petro Poroshenko taking part in the opening of a memorial to Ukrainians killed by Polish partisans during the ceremony in the Polish village of Sahryn, 125 kilometers (77 miles) across the border. The presidents of Poland and Ukraine held separate ceremonies marking 75 years since a WWII-era ethnic conflict between their nations claimed thousands of lives, as a row over history continued to sour relations between the neighbours. Discord over the TheVolhynia massacres between 1943 and 1945 has led to a diplomatic chill between Kiev and Warsaw, whose relations deteriorated after the nationalist Law and Justice (PiS) party came to power in Poland in 2015. Polish President Andrzej Duda attended a mass commemorating the Polish victims of the conflict in Lutsk, a city in Ukraine's western Volhynia region. / AFP PHOTO / UKRAINIAN PRESIDENTIAL PRESS SERVICE / MIKHAIL PALINCHAK / RESTRICTED TO EDITORIAL USE - MANDATORY CREDIT "AFP PHOTO / ULRAINIAN PRESIDENTIAL PRESS SERVICE / MIKHAIL PALINCHAK" - NO MARKETING NO ADVERTISING CAMPAIGNS - DISTRIBUTED AS A SERVICE TO CLIENTS
