At least 14 people were killed when twin explosions caused by suicide bomb attackers struck near a police station in Damascus Tuesday, state television said, updating its earlier toll.
"The number of casualties after a twin suicide attack in Marjeh square has risen to 14 dead and 31 injured," said the broadcaster.
"The two suicide explosions took place near a police station," it added.
The Syrian Observatory for Human Rights also reported the blasts, but put the toll higher at 15.
"The number of people killed after two explosions in Marjeh square in Damascus has risen to 15," said the Britain-based activist group.
One of the blasts "was caused by a suicide bomb attacker who blew himself up inside the police station", said the Observatory, revising its earlier reports.
"A second explosion took place just outside the police station," the group said, without elaborating on the nature of that blast.
"The number of casualties is expected to rise because several of the wounded are in critical condition," added the Observatory, which relies on a network of activists, doctors and lawyers for its reports.
Areas of central Damascus have suffered frequent bomb attacks through the course of Syria's 26-month war. Most attacks were claimed subsequently by the jihadist Al-Nusra Front.
