BBC: Hundreds of Fatah gunmen have stormed Hamas-controlled institutions in the West Bank, including the Palestinian parliament building in Ramallah.
The gunmen reportedly tried to seize the Palestinian Legislative Council's second deputy speaker, Hassan Khuraishah, but staff intervened.
Fatah supporters also took over the Hamas-controlled council in Nablus.
The clashes came after Fatah was ousted from Gaza by Hamas, ending a week of clashes which left more than 100 dead. Fatah militants storm parliament (more)
