ROUGH CUT (NO REPORTER NARRATION)<br /> <br />STORY: Clashes resumed on Tuesday between Lebanese militias who back opposing sides of Syria's war and 21 fighters were arrested by the army as it pursued a six-month-long mandate to end bloodshed battering the city of Tripoli.<br /> <br />The conflict between the majority Sunni Muslim Bab al-Tabbaneh district and the adjacent Alawite neighborhood of Jebel Mohsen in Tripoli has killed over 100 people this year. But residents, fighters and a local politician told Reuters on Tuesday it was unlikely to end soon despite army efforts.<br /> <br />The two neighborhoods have been in on-off conflict since the 1980s but the 2-1/2-year-old civil war in neighboring Syria pitting Alawite President Bashar al-Assad against majority Sunni rebels has opened old wounds on both sides in Tripoli, and fighting has become more frequent and intense.<br /> <br />The latest clashes started after repeated attacks on Alawite targets over the last week in which several people were wounded.
