(Al Jazeera) – At least 52 Palestinians were killed on Monday in Gaza and more than 2,410 others wounded as the Israeli army fired live ammunition, tear gas and firebombs at protesters assembled along several points near the fence with Israel. The demonstrations, which coincided with protests against the opening of the US embassy in Jerusalem, are part of a weeks-long protest calling for the right of return for Palestinian refugees to the areas they were forcibly expelled from in 1948.
