President Mahmoud Abbas called Sunday for renewed talks between Fatah and Hamas, a day after the latest clashes between the two rival Palestinian movements killed at least 11 people and prompted 180 or more Fatah supporters to flee the enclave. Over 100 people were injured in eastern Gaza City's Sheja'eya neighbourhood during gunbattles, which erupted early Saturday after Hamas security forces attempted to arrest members of the Fatah-allied Helles clan in its stronghold. On Sunday, a relative calm returned to Gaza following what was termed the worst fighting since Hamas took over the enclave last year.
