The Thursday attack killed two women and wounded several other people, reports say.
The area has been targeted by the militants fighting government forces several times in the past.
On October 22, three civilians were killed in a similar attack in the Damascus countryside of Jaramana.
Syria has been gripped by deadly unrest since 2011. According to reports, the Western powers and their regional allies -- especially Qatar, Saudi Arabia, and Turkey -- are supporting the militants operating inside Syria.
Militants from countries including the United States, Canada, France, and Britain are fighting in Syria.
Authorities estimated that around 1,000 militants from across Europe are currently fighting in Syria -- compared to just 250 in late 2012.
According to the United Nations, more than 100,000 people have been killed and millions displaced in the violence.
The UN also says more than four million other Syrians will be forced out of their homes in 2014 by the escalating conflict in the country.
Two million Syrians are expected to take refuge outside the country while another 2.25 million are predicted to be internally displaced in the next year.
