Syrian state TV says seven people were killed and more than 40 wounded by a car bomb in the port city of Latakia.

The report says the blast went off in the city's Hamam Square on Wednesday, but provided no further details.

Latakia is a stronghold of Syrian President Bashar Assad, whose forces are locked in a civil war with an array of rebel groups, including Islamic militants. Last month, rebels shelled Latakia, killing six people and wounding 19.

Still, Latakia has largely remained on the sidelines of the conflict that began in 2011, and explosions in the city have been rare.
