'Deadly blasts' shake Syrian capital Damascus
At least 27 people have been killed and 97 wounded in two explosions in the Syrian capital Damascus, officials say.
State TV described the blasts as "terrorist" attacks. Preliminary reports suggested vehicles packed with explosives had been detonated, it said.
It said intelligence and police buildings were hit and the cause was not known.
Details of the reports cannot be independently verified.
Foreign journalists only have very restricted access to Syria.
Dozens of people have been killed in bomb attacks in Damascus and the second city Aleppo in recent months, which the government also blamed on terrorists.
The opposition has accused the authorities of staging some of those incidents.Gruesome pictures
The two explosions aimed at security buildings are another breach of the tight security apparatus control here in Damascus. Although all security buildings are sealed off with barricades, the government claims these were car bomb explosions.
They happened in the early hours of the morning on a weekend so there was hardly any movement in the street. But the timing of the blasts will raise eyebrows. They occurred a day before UN-Arab League envoy Kofi Annan is to launch his mission by sending a technical team to Damascus. Mr Annan wants to find a political solution to the crisis but President Assad said this would not succeed while terrorist groups were operating in Syria.
Similar explosions took place in Damascus just as an Arab League mission arrived in the country. Opposition groups blame the government for such attacks and say they are aimed at discrediting them.
The latest blasts came two days after the first anniversary of the uprising against President Bashar al-Assad, which UN estimates say has left more than 8,000 people dead.
State TV showed pictures of charred bodies, burned-out vehicles and bloodstains on the streets, as well as injured people being treated in hospital.
It described one body as being that of a terrorist.
It said buildings housing the criminal police and aviation intelligence had been targeted.
Opposition sources also said security buildings had been hit.
One activist told AFP news agency the first blast occurred at 07:30 local time (05:30 GMT), and was followed by a second more powerful explosion.
"All our windows and doors are blown out," local resident Majed Seibiyah, 29, told the Associated Press news agency.
"I was sleeping when I heard a sound like an earthquake. I didn't grasp what was happening until I heard screaming in the street."
Fresh anti-government protests were held on Friday in cities across Syria.

And there was a return of violence to the Damascus suburbs - the first significant fighting there since government forces imposed military control some weeks ago.
Clashes between rebel fighters and the army were reported in several other parts of the country.
President Assad insists his troops are fighting "armed gangs" seeking to destabilise Syria.
On Friday, UN and Arab League special envoy Kofi Annan renewed calls for an end to fighting and for unimpeded humanitarian aid for Syria.
Speaking to UN Security Council members, he said he was sending a team to Damascus to discuss setting up a new international monitoring mission.
The international community remains divided on Syria, with Russia and China both blocking UN Security Council resolutions on Syria and aid groups from 27 countries urging them to condemn the government's use of violence.
But the two permanent members have backed Mr Annan's peace mission.
