Israeli airstrikes in Gaza have killed at least 10 Palestinians over the past 24 hours. In the biggest raid, an Israeli bomb destroyed a two-story building belonging to Hamas. The bomb killed two members of Hamas and wounded 45 people, including civilians who were buried in the rubble. Five more Palestinians died when Israeli war planes bombed a Hamas headquarters building east of Gaza City. A third Israeli airstrike targeted a pickup truck near the southern town of Rafah. It killed three people — a father and his two teenage sons. Israeli troops and tanks have also moved across the Gaza border. Hamas accused Israel of colluding with Fatah in a battle for dominance over Gaza. A spokesperson for Israeli Prime Minister Ehud Olmert said the Israeli attacks were justified because Hamas is firing rockets into southern Israel.

Miri Eisen: “We won’t allow them to use their violence, their terror, against Israel. Israel knows how to respond. We will do all defensive measures to be sure that our citizens are safe. We will not be dragged by the Hamas into the mire of Gaza.”

Hamas has vowed to keep carrying out rocket attacks. Paramedics in Israel said at least three Israelis were injured this morning in a rocket attack on the town of Sderot. On Thursday, Hamas rockets hit a synagogue and a school.

Hamas spokesperson Ayman Taha: “We will not be quiet for long with these continued crimes, and we will not stand with our hands tied. We’re ready to launch any type of attack, by any means and equipment necessary, and in all the cities. We will choose the right time and place.”

In Washington, the Bush administration has praised Israel for showing what it described as “great restraint.” But the Arab League has denounced Israel for exploiting Palestinian infighting.
