Libya's newly elected parliament is turning to the United Nations, asking for an "international intervention" as militia violence rages across the country.

Libya is undergoing its worst spasm of violence since the 2011 ouster and killing of former dictator Muammar Qaddafi. Thousands have fled the country, including diplomats and foreign nationals. Scores of embassies have closed down and international organizations have shut their offices.

Lawmakers convened on Wednesday in Libya's easternmost city of Tobruk, far from weeks-long militia fighting over the international airport in the capital, Tripoli, and clashes in the country's second-largest city, Benghazi.

They adopted a resolution asking the Security Council for help. It passed with 111 votes in favor from among 124 lawmakers present at the session.

Meanwhile, random shelling in Tripoli killed three people overnight.
