At least one Palestinian has been killed and fifteen injured during clashes between the Palestinian security forces and fighters associated with the Al-Aqsa Brigades, the armed wing of the Fateh movement, in the northern West Bank town of Tubas Saturday evening. According to local sources, the fighting broke out when the gunmen laid siege to the building housing the Palestinian national security forces, firing live ammunition and eventually setting the building on fire.

Raed Abd ar Raziq, 30, was killed in the clashes that ensued. Fifteen others were injured, ten of whom are in critical condition at the hospital, according to local medical sources.

The exact reasons for the attack are unknown, although tension has been high between the Hamas-led government forces and the Fateh party opposition in recent weeks.
