A car bomb explosion in southern Damascus killed at least seven people and injured 15 on Tuesday, Reuters reported.
The reported number of deaths and injuries came from he Syrian Observatory for Human Rights, a rights group from the U.K. that supports the rebel opposition.
The explosion hit the district of Tadamon -- an area where rebels have been fighting against Syrian President Bashar Assad's regime for months. It is not clear what or whom the bomb was targeting.
State new outlets said "terrorists" were responsible for the car explosions, although they generally use that word to describe rebels who are fighting against Assad's government.
"Three citizens were martyred and others were injured in terrorist suicide bombing using a car bomb which took place in al-Tadamun neighborhood in Damascus," the Syrian Arab News Agency said.
According to the Britain-based Observatory, multiple building were destroyed in the explosion.
Syrian rebels recently launched a new offensive against the government, but Assad's forces have fought back and successfully organized blockades that prevent rebels from moving supplies.
An activist said the newly pushed offensive is not likely to be a success.
"The regime's top forces are there," he said. "We on the ground consider these to be 'show' operations from the Free Army, especially in cooperation with Ahrar al-Sham and Nusra. It's a war of attrition. There is no winner and no loser."
The Syrian civil war has resulted in nearly 100,000 deaths since it began in March 2011, in addition to leaving over 1 million people displaced and fleeing to neighboring countries.
