"Flying chairs and punches thrown by women students at a Gaza university this week may seem a rather minor manifestation of the factional fighting that has riven Palestinian society over the past year or so. But with Hamas and Fatah still smarting from bloody armed clashes in 2007, when the Islamists routed President Mahmoud Abbas's PLO forces in the enclave, the scuffle shows how deep the rift runs."
