At least nine people were killed and dozens injured on Saturday in two explosions in a suburb of the Syrian capital Damascus, a monitoring group reported.
The Syrian Observatory for Human Rights added that the synchronized attacks in Damascus' southern area of Sayeda Zeinab resulted separately from a car bomb and a suicide assailant.
Syria's state-run news agency SANA said eight people were killed and 13 injured in what it called "terrorist" attacks.
No one has claimed responsibility.
Sayeda Zeinab houses a shrine revered by Shiite Muslims.
The radical Sunni Islamic State, which rules areas in war-torn Syria, previously took credit for similar attacks in the same area.
