A site of prayer became a battlefield in Jerusalem on Friday night after clashes broke out at a mosque between Israeli police and thousands of Palestinians. Police were in riot gear as they fired rubber bullets and stun grenades while Palestinians hurled stones at the Al-Aqsa Mosque. Over 170 Palestinians and at least six officers were injured, according to medics and police on the scene. The city of Jerusalem sits at the core of the Israeli-Palestinian conflict. Anger has been mounting over the potential eviction of Palestinians from homes on land claimed by Jewish settlers. That's led to a long-running legal case which evolved into nightly clashes in East Jerusalem and the occupied West Bank during the Muslim holy month of Ramadan.On Friday, smaller scuffles also broke out near Sheikh Jarrah, a neighbourhood overwhelmingly populated by Palestinian families - many of which face potential eviction.There, police used water cannon mounted on armored vehicles to disperse several hundred protesters. Calls for calm and restraint poured in from the U.S. and the United Nations.The European Union and the neighbouring country of Jordan voiced alarm at the possible evictions. Israel's Supreme Court will hold a hearing on those evictions on Monday, the same day the country marks Jerusalem Day.That's the annual celebration of its capture of East Jerusalem during the 1967 Middle East war.
