DAMASCUS, Syria (CBS/AP) -- Twin suicide car bomb blasts ripped through an upscale Damascus district Friday, targeting heavily guarded intelligence buildings and killing at least 40 people, Syrian authorities said.
The blasts came a day after an advance team of Arab League observers arrived in the country to monitor Syria's promise to end its crackdown on protesters demanding the ouster of President Bashar Assad. Government officials took the observers to the scene of the explosions and said it backed their longtime claims that the turmoil is not a popular uprising but the work of terrorists.
CBS News' George Baghdadi reports, however, that opposition members have remained skeptical - even since the deal with the Arab League was signed - that the Assad regime will allow the observers to operate with anything resembling independence.
The blasts were the first such suicide bombings in Syria since the uprising began in March, adding new and ominous dimensions to a conflict that has already taken the country to the brink of civil war.
"We said it from the beginning, this is terrorism. They are killing the army and civilians," Deputy Foreign Minister Faysal Mekdad told reporters outside the headquarters of the General Intelligence Agency, where bodies still littered the ground. State TV said initial investigations indicated possible involvement by the al Qaeda terror network.
Alongside him, the head of the observer advance team, Sameer Seif el-Yazal, said, "We are here to see the facts on the ground. ... What we are seeing today is regretful, the important thing is for things to calm down."
An opposition leader raised doubts over the authorities' version of events, suggesting the regime was trying to make its case to the observers.
Omar Idilbi, a member of the Syrian National Council, an umbrella group of regime opponents, called the explosions "very mysterious because they happened in heavily guarded areas that are difficult to be penetrated by a car."
"The presence of the Arab League advance team of observers pushed the regime to give this story in order to scare the committee from moving around Syria," he said, though he stopped short of accusing the regime in the blasts. "The second message is an attempt to make the Arab League and international public opinion believe that Syria is being subjected to acts of terrorism by members of al Qaeda."
The blasts went off outside the main headquarters of the General Intelligence Agency and a branch of the military intelligence, two of the most powerful of Syria's multiple intelligence bodies. Outside the two buildings, mutilated and torn bodies lay amid rubble, twisted debris and burned cars in Damascus' upscale Kfar Sousa district. Bystanders and ambulance workers used blankets and stretchers to carry bloodstained bodies into vehicles. All the windows were shattered in the nearby state security building, which was targeted by the other bomb.
The two blasts went off within moments of each other at 10:15 local time (0815GMT) Friday, a weekend day, echoing across the city.
"The explosions shook the house; it was frightful," said Nidal Hamidi, a 34-year-old Syrian journalist who lives in Kfar Sousa. He said gunfire was heard immediately after the explosion and said apartment windows in a 200-yard (meter) radius from the explosions were shattered.
A military official told reporters that more than 40 people were killed and more than 100 wounded. He spoke to reporters on condition of anonymity in accordance with military rules. Earlier, state TV said most of the dead were civilians but included military and security personnel.
Maj. Gen. Rustom Ghazaleh, who heads the targeted military intelligence department, said the attacks were proof of a foreign project to strike at Syria. "We will fight this project until the last drop of blood," he declared.
A Syrian military official said the explosion targeting the military intelligence building, the bigger of the two blasts, weighed more than 660 pounds (300 kilograms) and gouged a crater into the ground that was 2 yards deep and 1.5 yards wide. It killed 15 people, among them a retired brigadier general.
The blasts came as the Syrian government escalated its crackdown ahead of the arrival Thursday of the Arab League observers. More than 200 people were killed in two days this week.
Syria's violent crackdown on opposition protesters during the past year has, however, prompted the formation of a rebel militia, known as the Free Syria Army, members of which met CBS News correspondent Clarissa Ward when she sneaked into the closed nation posing as tourist several weeks ago.

David Hartwell, Middle East political analyst at IHS Jane's in London, said the timing "is certain to be viewed with suspicion by the opposition."
"The start of the monitoring mission has been overshadowed by the attacks in Damascus, a fact that government critics may highlight as fortuitous and more than a little coincidental," he said.
He added that the Arab League "will need to work extremely hard" to convince observers and the opposition that it is not being played by the Syrians in an effort to stall for time.
The United Nations says more than 5,000 people have been killed since March, when the uprising began, prompting an immediate crackdown that continues nine months later. With the arrival of Arab observers, the government has been eager to make its case, saying Thursday that 2,000 of its security personnel and soldiers have been killed in the turmoil.
