Five Shi'ite Muslims on Lebanon's Cabinet resigned on Saturday after the government refused a demand to include more members of the militant group Hezbollah.
Hezbollah representatives said the ministers were from their organization and its ally, the Amal movement.
Lebanese Prime Minister Fuad Siniora rejected the resignations. He said he wanted the ministers to remain in the government.
Hours earlier, officials broke off talks on whether to give Hezbollah and its allies a more decisive role in the Sunni-led government.
Anti-Syrian leaders rejected the demand from the Shi'ite groups. The Shi'ites have threatened mass demonstrations if their demand is not met
Lebanese Christian leader Michel Aoun said there are no plans for additional talks on the issue. Some political leaders tried to ease concerns of possible street clashes because of the decision.
