Soldiers stand guard by the monument of World War Two at Westerplatte, outside of Gdansk September 1, 2009. European leaders will commemorate on Tuesday the 70th anniversary of the outbreak of World War Two at ceremonies in Poland already clouded by disputes over historic responsibility that pit Russia against the West. Russian Prime Minister Vladimir Putin's speech in the Polish Baltic port of Gdansk will be keenly scrutinised by Poles, Balts and others irked by what they see as Moscow's attempts to whitewash Soviet dictator Josef Stalin's role 70 years ago.[Xinhua/Reuters]
