Heavy gunfire at Libyan parliament

Libyan interim parliamentLibya's General National Congress building

Heavy gunfire has been heard outside the Libyan interim parliament in the capital Tripoli.

MPs fled the building after gunmen attacked it. There are reports that supporters of a rogue officer, Khalifa Haftar, carried out the assault.

His forces launched a major air-and-ground attack on Benghazi in the east on Friday, prompting the government to declare a no-fly-zone there.

Authorities are struggling to contain militias that control parts of Libya.

A planned new constitution remains unwritten and the country has had three prime ministers since March.

The recent fighting in Benghazi – where the uprising against the former regime of Col Gaddafi began in 2011 – pitted Gen Haftar's forces against Islamist militants.

Dozens of people were killed.
