Militant Palestinian groups, Islamic Jihad and the Al-Aqsa Martyrs' Brigade, on 12 December both claimed responsibility for an attack on seven Israeli pilgrims at Joseph's Tomb in the West Bank city of Nablus, local radio reported. 'This attack was a rapid answer to the massacre of our martyrs in the Rafah refugee camp,' said a statement received by AFP, referring to the six Palestinians killed during an Israeli incursion in the Rafah refugee camp the previous day. All of the injured pilgrims, two of whom were seriously wounded, were evacuated from the scene by the Israeli military.
