A suicide bomber blew himself up in central Damascus, causing deaths and injuries, Syrian state television reported, with at least four reported killed and 17 injured.

"A terrorist suicide bomber wearing an explosive belt blew himself up in the Jebbeh district of the Jisr al-Abyad neighbourhood, causing deaths and injuries," state television said on Tuesday.

The Syrian Observatory for Human Rights, a Britain-based monitoring group, said that the target appeared to be a government building.

Suicide bombings have repeatedly targeted the capital in the bloody 33-month conflict pitting forces loyal to President Bashar al-Assad against rebels seeking his ouster.
