A Syrian government official says a car bomb has exploded near police headquarters in central Damascus.

Residents reported hearing a huge explosion that rattled the Syrian capital just after sundown Sunday.

The official, who spoke on condition of anonymity in line with government policy, told The Associated Press the blast was caused by a car bomb that blew up in the Fahameh district near police headquarters.

It was not immediately clear whether there were any casualties or damage from the explosion.

Syrian TV described the blast as a "terrorist" attack.

Damascus and the northern city of Aleppo have both become frequent targets for car bombs and suicide blasts.
