Army units have deployed in Lebanon’s northern port of Tripoli after sectarian strife in Syria spilled over the border.
Clashes in the city between Alawite supporters of Syria’s President Bashar al-Assad and Sunni Muslims have claimed at least nine lives.
Assad is from the Alawite sect, an offshoot of Shi’ite Islam, whereas the revolt against him has been led by the majority Sunni Muslims.
A small Alawite minority live in Tripoli, a Sunni city where many are enraged by the Syrian regime’s crackdown.
After earlier clashes this year, the latest violence followed the arrest of a Sunni cleric accused of terrorism. His supporters claim he had simply been helping Syrian refugees.
