A masked Palestinian youth throws a petrol bomb towards Israeli security forces during clashes at the Qalandia checkpoint between Jerusalem and Ramallah, in the Israeli-occupied West Bank, on October 6, 2015. Palestinian president Mahmud Abbas said he wanted to avoid a violent escalation with Israel, his most direct comments since unrest has spread in recent days and provoked fears of a new uprising. His comments came as Prime Minister Benjamin Netanyahu pledged a crackdown and Israel, in a show of force, demolished the homes of two Palestinians who carried out attacks last year.
