Calm returned to Tripoli after Lebanese army troops arrested a number of gunmen on the streets of the northern port city.
News reports on Monday said that among the detainees was Mohammed Ahmad Arour, a supporter of pro-opposition former Premier Omar Karami.
The arrests were made following a half-hour clash on Sunday between Lebanese troops and armed Arour followers at Bab al-Tabbaneh near Tripoli.
Two Lebanese army soldiers were wounded in the fight which broke out shortly before 6 pm.
The clash erupted when Arour refused to stop at a Lebanese army checkpoint in Bab al-Tabbaneh, the state-run National News Agency reported.
It said troops pursued Arour and arrested him after a thirty-minute clash that left two army troops wounded, one of them seriously.
