CNN:
Fatah-Hamas battles rage across Gaza as cease-fire falters
GAZA CITY (CNN) — Gunfire rattled across Gaza City early Friday as fighters from the ruling Palestinian faction Hamas fought a pitched battle with rivals from Palestinian Authority President Mahmoud Abbas’s Fatah movement near a Hamas stronghold.

The fierce midnight shootout at Gaza’s Islamic University came after a day of clashes between Hamas and Fatah that left five dead and 45 wounded, shredding a cease-fire the two factions reached earlier this week. The fighting spread to districts all around Gaza City, with Abbas’ office and residence coming under fire at one point.

Police under Fatah’s control fought their way onto the university campus and seized hundreds of rocket-propelled grenades and more than 2,000 weapons, Palestinian security sources said.

Fatah also claimed to have detained six Iranian military officers, including a colonel and four men it called “chemical experts.” Hamas denied the claims, for which there was no independent confirmation early Friday. (Posted 7:43 p.m.)
