Two suicide bombings in Damascus are reported to have killed at least 40 people Friday. According to Syria's state media, Al Qaeda terrorists were to blame.
Twin car bombs were set off outside two buildings used by security and intelligence services, SANA news agency reported, both said to be in the capital's south-west Kfar Sousa district.
More than 40 people were killed and over 100 injured, an unnamed military official told the Associated Press.

Some military personnel were killed, but the majority of victims were civilians, SANA said. Its report was accompanied by graphic photos of corpses and body parts.
"Preliminary investigations indicated that that the criminal attack carries the blueprints of Al Qaeda," the agency reported.

Activists have called for nationwide protests against the mission to take place after Friday prayers, under the slogan "Protocol of death, a license to kill," Al Jazeera reported. The organizers accuse President Bashar al-Assad's government of trying to stop the League involving the UN Security Council by agreeing to allow in monitors while continuing to crack down on protesters.
When the Syrian Foreign Ministry agreed to the observer mission, it expressed confidence that the team would find evidence to support the government's claims that armed terrorist gangs—not state security forces—were responsible for much of the violence.
Deputy Foreign Minister Faysal Mekdad visited the scene of Friday's bombings, the AP reported, where he repeated the official version of events:
"We said it from the beginning, this is terrorism. They are killing the army and civilians."
Accompanying Mekdad, the head of the Arab League's advance observer team, Sameer Seif al-Yazal, stressed that he and his colleagues were in Syria to "see the facts on the ground."
