Four explosions rocked the Jaramana suburb of the capital Damascus early on Wednesday morning, killing and injuring undisclosed number of people, Syria' s al-Ekhbaria TV said.

The TV said the blasts were triggered by two booby-trapped cars and two explosive devices that went off in several areas of Jaramana, causing deaths and injuries.

The latest blasts came apparently to reduce pressure on the armed rebels currently surrounded by the government troops in the Damascus' suburb of Daraya, the latest scene of intense clashes.

The Syrian administration has said the army is fighting thousands of al Qaida fighters in several areas nationwide.
