Libya's internationally recognized government has rejected a U.N. proposal for a power-sharing arrangement with rival Islamist-led authorities that was intended to bring peace to the north African nation.

Farraj Abu Hashem, spokesman for the internationally recognized parliament, said Monday that they will not sign the agreement to form a unity government because the U.N. refused to exclude amendments added by the Islamist authorities without their consent.

Libya slid into chaos after the 2011 toppling and killing of longtime dictator Moammar Gadhafi. The internationally recognized government is confined to the far east while a rival Islamist-led government is based in the capital, Tripoli.
