Libya's elected parliament voted on Monday to suspend its participation in a UN-sponsored dialogue between Libya's rival conflict parties, vying for control of the oil producer, a lawmaker said.
The United Nations has hosted several rounds of talks between the conflict parties since September, inside and outside Libya, to help defuse a violent power struggle threatening to break up the North African country.
Lawmaker Essam al-Arabi told Reuters the House of Representatives had voted to suspend its participation.
The house has been based in the east, like the internationally recognized government, since a faction called Libya Dawn seized the capital Tripoli in August, reinstating the previous assembly and installing a rival government.
Arabi gave no reason for the move.
Islamic State militants have conducted several attacks and suicide bombings across Libya in the past few days, undermining the prospects for the talks.
