Israeli helicopters fired four missiles at a car in Gaza City on Monday afternoon, killing two Palestinians. More than 25 people were wounded. Palestinian sources said that the targets of the attack were members of Hamas armed wing. A third activist was wounded. The attack took place near the government complex in Gaza City. In the past two weeks, Israel has killed 10 Hamas members and three bystanders in five such attacks. In the city of Nablus, hundreds of students threw stones at Israeli tanks and jeeps in several locations. Troops fired tear gas, rubber bullets and live rounds to disperse the crowds, witnesses said, according to the AP. A Palestinian threw a firebomb at a tank near the main square, where scores of stone-throwers were assembled. The top of the tank caught fire, said Palestinian rescue worker Ala Aratrut, who saw the incident. "A soldier from inside the tank began shooting randomly. The top of the tank was going round while the shooting went on," said Aratrut, a witness. A teenager fell to the ground after being shot in the head, the rescue worker said. Doctors said the boy, age 15, was in critical condition. **Arafat-Abbas*** Meanwhile, a power struggle between Palestinian leader Yasser Arafat and his prime minister, Mahmoud Abbas, is intensifying, with fights over key appointments and control of security forces. On their part, members of the Palestinian Legislative Council (PLC) are denying heavy American pressure lobbying them against introducing a no-confidence vote against Palestinian Prime Minister Abu Mazen's government. They have also said that they are reviewing several proposals for resolving the growing conflict between Abu Mazen and Arafat. According to the reports, American officials have told Palestinian legislators that should the council vote against Abu Mazen's government; the US will withdraw its support for the 'roadmap' - which proposes the establishment of a Palestinian state by the year 2005. **PHOTO CAPTION*** Palestinians try to put out a fire after an Israeli helicopter missile strike in Gaza City, Monday, Sept. 1, 2003.
