Car bomb kills 13 in Syria's Homs - monitoring group
Another 40 people were wounded in the explosion in the mainly Alawite Zahraa neighbourhood, it said. Some of the dead were security forces loyal to President Bashar al-Assad, an Alawite, who is fighting a three-year revolt against his rule.
Car bombs have become frequent in Homs in the past weeks, in particular since Assad's forces moved into previously rebel-held areas of the city this month.
The uprising against Assad began as peaceful protests but became militarised after heavy crackdown by his forces, taking on an increasingly sectarian nature, pitting majority Sunni Muslims against Alawites, followers of an offshoot of Shi'ite Islam.
Syria became a magnet for foreign al Qaeda-linked fighters who now control some rebel-held areas of the country.
