A Palestinian man walks past Israeli security personnel at an entrance to Jerusalem's Old City October 9, 2015. Four Israelis have been killed in stabbings in Jerusalem and a drive-by shooting in the occupied West Bank since last week, and there have been several such attacks by Palestinians within Israel that caused injuries but no fatalities. Three Palestinians have been shot dead and scores injured in clashes with Israeli security services, triggering fears of a new Palestinian uprising or intifada. Israeli police spokesman said on Friday that they will only permit Palestinian men over the age of 45 to enter the Old City. REUTERS/Baz Ratner
