The spokesman for Libya's internationally backed parliament says it has voted "no confidence" in the country's U.N.-backed government.

The development is a major blow to international efforts to resolve the crisis in the deeply divided North African country.

The spokesman, Abdullah Ablahig, says 101 lawmakers were present Monday, enough to reach quorum for the vote. He says 61 supported it, 39 abstained and one member voted to support the government.

It's unclear what happens next. Some lawmakers claim the vote would automatically dissolve the government set up under a U.N. deal, while its supporters dispute this.

Libya's parliament is seated in the eastern city of Tobruk. The U.N.-backed government is based in Tripoli, the country's capital.

Libya has been mired in conflict since the 2011 ouster of dictator Moammar Gadhafi.
