Syrian and Palestinian protesters hold up flags out of the offices of the United Nations in Damascus, capital of Syria, to denounce the Israeli raid on six aid ships in international waters, May 31, 2010. Israeli commandos on Monday stormed six ships carrying hundreds of pro-Palestinian activists on an aid mission to the blockaded Gaza Strip, killing at least 10 people and wounding dozens after encountering unexpected resistance as the forces boarded the vessels.
