HAMAS MOVEMENT CALLED OFF A 16-MONTH-OLD TRUCE WITH ISRAEL ON FRIDAY AFTER PALESTINIANS SAID ISRAELI ATTACKS ON THE GAZA STRIP KILLED 10 PEOPLE, INCLUDING THREE CHILDREN, REUTERS REPORTED. THERE WAS NO IMMEDIATE COMMENT FROM ISRAEL OR FROM PALESTINIAN PRESIDENT MAHMOUD ABBAS. "THE ISRAELI MASSACRES REPRESENT A DIRECT OPENING BATTLE AND THAT MEANS THE EARTHQUAKE IN THE ZIONIST CITIES WILL RESUME AND THE HERDS OF OCCUPIERS HAVE NO CHOICE BUT TO PREPARE THE COFFINS OR THE DEPARTING LUGGAGE," HAMAS'S ARMED WING SAID IN A STATEMENT. EARLIER ON FRIDAY, ISRAELI AIR STRIKES AND ARTILLERY FIRE KILLED 10 PALESTINIANS, INCLUDING THREE CHILDREN ON A CROWDED GAZA BEACH, THE HIGHEST PALESTINIAN DEATH TOLL IN A SINGLE DAY SINCE LATE 2004, PALESTINIAN OFFICIALS SAID. SEVEN PEOPLE, INCLUDING FIVE FROM THE SAME FAMILY, WERE KILLED IN A SHELLING OF THE BEACH, WHICH PALESTINIAN SOURCES SAID CAME FROM ISRAELI SHIPS. THE THREE CHILDREN DIED WHILE PLAYING IN THE SAND WHILE THEIR SISTER, WHO HAD BEEN SWIMMING, SURVIVED. ABOUT 20 MORE PEOPLE WERE INJURED IN THE ATTACK, WHICH PALESTINIAN PRESIDENT MAHMOUD ABBAS CALLED "A BLOODY MASSACRE". THE ISRAELI ARMY SAID IT WOULD INVESTIGATE THE SHELLING.
