A seven-year-old girl in southeast Damascus blew up herself on Friday inside a police station, injuring three security officials.
According to media reports, the girl was wearing a remote-controlled explosives-laden belt when she entered the police station.
“A seven-year-old girl entered the police station, carrying a belt that was detonated from afar,” Al-Watan daily, a paper which is close to the Bashir al-Assad government, posted on its Facebook page.
Police said that she had appeared lost and asked to use the bathroom when the explosives went off.
Although rebel groups have fired rockets and mortar rounds into the capital, explosions inside the city itself are rare.
Syrian state news agency SANA said that earlier there were preliminary reports about a terrorist explosion at the Midan police station in Damascus.
The Syrian Observatory for Human Rights confirmed there had been a blast in Midan but said it could not specify the cause.
In early 2012, a suicide bomber killed 26 people when he blew himself up in Midan. More than 310,000 people have died since Syria's conflict broke out in 2011.
