Top PLO officials met Friday to discuss Palestinian Authority Chairman Mahmoud Abbas' next move after he declared that coalition talks with Hamas have failed.
Abbas has two options - fire the Hamas-led government or hold a referendum on whether to call early elections. If he dismisses the Hamas ministers, a new government he appoints would be blocked in the Hamas-dominated parliament, leading to a constitutional crisis that could also force elections.
Recent polls have shown that Abbas' Fatah Party would not have enough support to oust Hamas in new elections.
Hamas has dismissed Abbas' declaration as a pressure tactic in the negotiations on forming a national unity government.
