Libya's capital was quiet early on Sunday, a day after the worst fighting there for two years killed 32 people and injured 159 as forces aligned with a parliament-backed administration failed to dislodge the Tripoli-based government.

Roads in the city were busy with motorists, shops were open and people were clearing away smashed glass and other debris from Saturday's violence, with burned out vehicles lining some streets in central Tripoli.

The fighting has raised fears of a wider conflict in Libya over the political standoff between Prime Minister Abdulhamid al-Dbeibah in Tripoli and Fathi Bashagha, who seeks to install a new government in the capital.
