The Ezzedine al-Qassam Brigades, the armed wing of Hamas, said it had fired four M75 rockets at Jerusalem, which lies 65 kilometres from the Palestinian enclave. It also claimed to have launched a rocket at Haifa, 165 kilometres away. There was no report of anything hitting the northern port city but the army said a rocket did fall on Hadera, 100 kilometres north of Gaza. Hamas militants also said yesterday they fired four rockets at Tel Aviv, 60 kilometres north of Gaza, etting sirens off across the city.
