Gunbattles Rage Between Hamas and Fatah

The militant group Islamic Jihad claimed responsibility for some of the rockets that landed in Israel, including one that hit a community center the southern town of Sderot. The army said the rocket caused some damage but nobody was hurt.

There was no immediate claim of responsibility for the attack that struck the Gaza home. In the past, similar cases of Palestinians being hurt by Palestinian rockets have led to backlashes against militant groups, whose attacks against Israel are generally supported by the public.

The boy, Samir al-Masri, suffered two broken legs, said Dr. Said Judeh of Kamal Adwan hospital. The boy's 4-year-old sister and 3-year-old brother were lightly wounded by shrapnel, said their uncle, Jad al-Masri.

Abbas, a moderate, has repeatedly called for an end to rocket fire, saying they only invite harsh Israeli retaliation.

In the West Bank town of Ramallah, Abbas said he hoped to hold a long-awaited summit with Olmert by the end of the year.

"We always showed our willingness to hold this meeting with Olmert, and it's no secret that we hope it will take place before the end of this year," Abbas said at a news conference with the visiting Italian foreign minister, Massimo D'Alema. "There is progress in preparations for this meeting."

The two leaders have repeatedly expressed readiness to meet for what would be their first summit. But preparations have bogged down amid disagreements over the agenda.

Abbas wants Israel to promise to release hundreds of Palestinian prisoners. Olmert has ruled out a prisoner release until Hamas-linked militants free an Israeli soldier they captured last June. Olmert's spokesman, Jacob Galanti, said he was not aware of firm plans for a meeting.
