Syrian state television and a rights group say a car bomb in the central city of Homs has killed several people.
The state television report says 14 were killed when the blast erupted outside a mosque in a pro-government district the city. Worshippers were leaving the mosque after attending Friday prayers.
The Syrian Observatory for Human Rights has confirmed at least nine deaths in the bombing, but the group warned the death toll could rise since many of the wounded are in critical condition.
The blast comes as government forces continue to advance in their offensive aimed at retaking rebel-held areas of Homs. Citizens there have seen heavy fighting over the last few days.
Activists say the Syrian conflict has killed more than 150,000 people since it began in March 2011.
