2030 GMT: The Tunisian news agency TAP says two Libyan ministers have crossed into Tunisia to join the regime's Foreign Minister, reportedly seeking a solution to the political crisis.
Health Minister Mohamed Al-Hijazi and Social Affairs Minister Ibrahim Cherif crossed into southern Tunisia. Foreign Minister Abdul Ati Al-Obeidi has met "several foreign parties" there, part of an effort to find a solution to a civil war in the north African country.
1850 GMT: Opposition and regime forces have clashed about 80 kilometres (50 miles) southwest of the Libyan capital Tripoli.
Sunday's fighting began when government forces tried to cut off the insurgents, who have moved into the plains from the western mountains, by attacking from behind.
The front line is now thought to have moved just north of Bir Ayad, near the town of Bir al-Ghanam. Bir al-Ghanam is only 30 kilometres (19 miles) south of Zawiya, a western gateway to Tripoli.
