Israeli forces fire tear gas at border protesters shortly after UN condemns 'excessive force'

Israeli soldiers fired tear gas at Palestinians gathered for a protest at the Gaza-Israel border on Friday, hours after the United Nations human rights chief criticized Israel for using "excessive force" against demonstrators there in recent weeks.

Around 40 Palestinians have been killed by Israeli gunfire at the border fence since a planned six-week protest began there on March 30, with no reports of Israeli casualties. The number of protesters usually swells to several thousands after Friday prayers.

Palestinian medical officials said at least three youths were wounded by Israeli fire near tent camps along the Gaza-Israel border, as some demonstrators hurled stones and rolled burning tires toward the fence.

Israel's foreign ministry had no immediate comment but the government has consistently said that it is protecting its borders and that its troops are following rules of engagement.
