Syrian state TV says the death toll from three blasts in a Shiite suburb of Damascus has reached 50, with more than 200 wounded.
It says the bombings on Sunday targeted a vegetable market in the afternoon during rush hour.
The Islamic State group claimed responsibility for a triple blast in Sayyida Zeinab, saying two IS fighters set off a car bomb before detonating their explosive belts.
Residents said the attack was about a kilometer (0.6 mile) from one of Shiite Islam's holiest shrines and did not damage it.
A triple explosion in Sayyida Zeinab killed 45 people last month.
