Syria's new authorities on Thursday launched a security crackdown in a coastal region where 14 policemen were killed a day before, vowing to pursue "remnants" of the ousted Bashar al-Assad government accused of the attack,

Syria's new rebel-led authorities say supporters of ousted President Bashar al-Assad have killed 14 interior ministry troops in an "ambush" in the west of the country. They say 10 other troops were wounded in the fighting on Tuesday near the Mediterranean port of Tartous, a stronghold of Assad's minority Alawite Muslim sect.

Syria's new rulers began an operation in western Tartous province, home to many from ousted leader Bashar Assad's Alawite sect. The killing of 14 police officers the previous day has irked the Islamist-led authorities.
