DAMASCUS - A series of deadly blasts rattled Syrian capital Damascus on Wednesday after the United States and its allies recognized the exiled Syrian opposition as the sole "legitimate representative" of Syrian people.

Wednesday started with two roadside bombs hitting Damascus' suburb of Jaramana in swift succession and killed one person and injured another five. The blasts took place near a school in the area.

Minutes later, two other roadside bombs rattled the parking lot of the main courthouse in Damascus, leaving great material damages and injuries among passersby.

Later in the evening, three blasts targeted Syrian Interior Ministry in Damascus' district of Kafar Souseh and killed at least five people.

One of the blasts near the ministry was caused by a booby-trapped car rigged with 200kg of explosives, the Interior Ministry said in a statement, adding that the other two were caused by explosive devices.

The death and injury toll includes civilians and members of the ministry, the statement said.

It is said that specialized authorities are analyzing the evidences from the blast site, adding that such acts will not dissuade it from cutting the roots of terrorism with the help of the Syrian army.

The Interior Minister Mohammad al-Shaar and other top officers are all fine and unscathed.

Meanwhile, pro-government Ekhbaria TV aired footage of an inside part of the ministry with broken walls and smashed windows.

A couple of hours after the ministry's blasts, an explosive device, believed to be affixed under a communal bus, went off in Damascus' district of Mazzeh 86, leaving three people killed and scores of others injured.

The blasts' pace and chaotic acts have dramatically surged after the United States and its regional and international allies recognized the exiled opposition coalition as the sole "legitimate representative" of the Syrian people.
