A gunbattle erupted this afternoon near the beach house of slain Libyan dictator Muammar Gaddafi's son, Saadi, in central Tripoli, AFP correspondents reported.
Thick smoke billowed from near the house as rival militias, using heavy machineguns, clashed in the mostly business district not far from luxurious hotels like Corinthia Bab Africa and the yet-to-open J W Mariott.
The cause was unclear, but some witnesses said the militias were fighting for control of the house.
Saadi fled Libya across its southern frontier to Niger in August during the fall of Tripoli that ended his authoritarian father's 42-year regime.
The Corinthia Bab Africa Hotel operations were not affected.
