Five people have been killed and 13 others hurt in clashes between two opposing forces that support the UN-backed government of Libya on Sunday, according to AFP, which cited medical sources.
The gun battle in Zaouia, some 40km (25 miles) west of the capital Tripoli, was between fighters linked to the defense ministry and those with ties to the interior ministry, local media reported.
The victims included a 10-year-old girl, the report said.
The fighting broke out over a dispute about fuel smuggling which is common in the country, a security source told AFP.
The clashes come amid a political crisis between backers of rival Libyan Prime Ministers Abdulhamid Dbeibah and Fathi Bashagha, whose forces are vying for control of the oil-rich nation.
Mr Dbeibah’s government was installed last year as part of a United Nations-led peace process, while Mr Bashagha was appointed by Libya’s eastern-based parliament in February.
