The Battalions of Struggle and Return, a previously anonymous offshoot of Fatah's Aksa Martyrs' Brigades claimed responsibility for the attack Thursday overnight, Israel Radio reported. The group added that the attackers managed to flee the scene. Police Chief Dudi Cohen and Jerusalem District Head Ilan Franco arrived at the scene after the attack. In every attack in the West Bank in recent month, a previously unknown Fatah linked group later claimed responsibility. Police said many attacks have been averted by security forces' work inside Palestinian towns.
