According to SANA the car bomb caused big flames and damaged surrounding buildings.

Four people were killed and 6 were wounded in the attack which happened near the Research and Tests Center, affiliated to the Syrian Ministry of Industry.

Damascus residents, already accustomed to incessant warfare within the Syrian capital, were making final preparations this weekend for an attack from outside, attempting to anticipate where American missiles might strike.

Tensions rose higher in the region after US rushed to dispatch its warships toward Syria, threatening to bomb several areas in the country, based on conflicting reports of an alleged chemical attack in the country.

The US-backed militants posted pictures and videos of an alleged chemical attack which they claimed the Syrian army was responsible for it.

The Syrian government, which has already called for UN action against several cases of chemical attacks by anti-Syria militants in the country, rejected the claims as baseless and paved the way for visiting UN team of inspectors to investigate the story.

Syria says the attack was actually carried out by the foreign-backed militants to open way for their Western and regional supporters to attack Syria.

Despite killing of at least 100,000 people in the massive insurgency in Syria, the US had said that it would enter the conflict if a chemical attack was carried out.
