Syrian forces killed at least 32 civilians on July 15, including 23 in the capital, Damascus, in an intensifying crackdown on protests against President Bashar al-Assad, activists said.
It was the highest death toll in the central neighborhoods of Damascus since the uprising erupted four months ago in the southern Hauran Plain near Syria's border with Jordan.
"Tens of thousands of Damascenes took to the streets in the main districts for the first time today; that is why the regime resorted to more killings," said one activist by telephone from Damascus. He declined to be named for fear of being arrested.
The killings prompted the opposition to cancel their planned National Salvation conference in Qaboun neighborhood of Damascus today after security forces killed 14 protesters outside a wedding hall where the conference had been due to take place, opposition leader Walid al-Bunni told Reuters.
"Secret police also threatened the owner of the wedding hall. We decided to cancel the meeting to save lives," Bunni said by telephone from Damascus.
Bunni said prominent opposition figures and activists would still hold a separate conference in Istanbul today.
