Today, a Palestinian man from the West Bank town of Tulkarem stabbed 13 passengers on a Tel Aviv bus seriously injuring four. The attacker Hamza Matrouk, 23, told police interrogators he was motivated by Israel’s 50-day summer war in Gaza and tensions at the al-Aqsa Mosque compound where right-wing Israeli politicians have have taken groups of religious-nationalists throughout the fall. Although no Palestinian political faction took credit for the attack, Israeli leaders were quick to place blame on Palestinian Authority head Mahmoud Abbas.
