Relatives of Palestinian Mahmoud Hmead, 22, who was killed by Israeli troops in Friday's clashes, mourn during his funeral in Gaza October 17, 2015. The unrest that has engulfed Jerusalem, Gaza and the occupied West Bank, the most serious in years, has claimed the lives of 39 Palestinians and seven Israelis. The tension has been triggered in part by Palestinians' anger over what they see as increased Jewish encroachment on Jerusalem's al-Aqsa mosque compound, which is also revered by Jews as the location of two destroyed biblical Jewish temples.
