Three Palestinians killed trying to stab Israelis

Three Palestinians were shot dead trying to stab Israelis in east Jerusalem and the West Bank on Saturday, as violence that has fuelled international concerns of a full-scale uprising showed no let-up. The deadly unrest that has raged for more than two weeks prompted a "very concerned" US President Barack Obama to call for calm as the UN Security Council held an emergency meeting on Friday. Including alleged assailants, 40 Palestinians have been killed since the violence erupted on October 1.
