DAMASCUS, Feb. 25 (Xinhua) -- A suicide car bomber detonated his explosive-laden vehicle near a military checkpoint in the Syrian capital of Damascus' suburb of al-Qaboun, close to Khumasieh company, activists and local media said, as witnesses said the blast has been followed by intense clashes at the eastern part of the capital.
The state-run SANA news agency said the blast shook the eastern suburb of al-Qaboun near al-Khumasieh Company, adding that unspecified number of people were killed or injured.
Meanwhile, activists' networks said the blast targeted a military checkpoint at the entrance of al-Qaboun and was followed by intense shooting which could be heard across several districts of the capital.
Witnesses at adjacent districts told Xinhua that "the rattling sound of clashes and shelling have reached God." They said the blast was followed by another one as the armed rebels waged attack from different hotspots near al-Qboun on the Abbasyeen Square.
Some online news websites said the Syrian troops responded to rebels' wide-scale offensive, killing many of them.
On Thursday, a powerful blast rocked a busy intersection of Damascus and claimed the lives of 56 people.
The government accuses radical groups affiliated with al-Qaida of being behind the series of explosions that have been rocking Syria over the past year.
