The decision took 36 hours of frantic discussions Syria has agreed in \'principle\' a senior Arab League mission into the country to try to help end the bloodshed, sources have told news agencies. But the spokesman said Syria was still studying the details.
Meanwhile, The Free Syrian Army (FSA) issued a video statement to explain its Wednesday attack on an Air Force intelligence base in Harasta.
The statement said: \"This is a response to exaggerated propaganda about a sophisticated operation against the air force intelligence base. This branch of the intelligence services has killed many defectors and civilians who have been arrested. It practises the most vile types of torture.
During our raid we found Iranians who are helping officers of the branch with their expertise. They [the Iranians] are providing them with logistical support to oppress the people\'s revolution. This is a criminal act by the regime and a country that supports the regime. It is a blatant interference in our country which we will not keep silent about.
That is why we decided to attack this branch. Even though the attack was only partially successful, we were able to free some of the detainees, military and civilians, thanks be to God.
We consider this and other branches a legitimate target, because we are military people and this is our duty. It is an accordance with international law and contrary to what the regime is doing by targeting civilian districts and unarmed protesters. Our people are looking to the free civilized world and won\'t wait for help from dictators. We as a Free Syrian Army make a pledge to God that we will sacrifice our blood for the freedom of our people and their dignity. We will attack the criminals of the Assad regime with an iron fist, and we and our people will topple Bashar al-Assadwith the help of God.\"
Rumours are abound of another attack set to take place today.
The Arab League suspended Syria earlier this week over its deadly crackdown on an eight-month-old uprising that the UN says has killed some 3,500 people.
The 22-member body gave Syrian president Bashar al Assad three days to halt the violence and allow in observers to monitor the situation.
It also pledged to introduce economic sanctions if the deadline is not met.
A source told Sky news: \"Syria has agreed to allow a senior Arab League mission into the country.
\"It has taken 36 hours of frantic discussions between Damascus and the Arab League to reach this agreement.
\"The deadline by the Arab League is Saturday. Syria is confident it has fulfilled all demands by the Arab League and is ready to sign as soon as the Arab League are ready.\"
The country\'s foreign minister is expected to make the announcement later.
It comes a day after Sky revealed that Britain, France and Germany are pushing for a UN vote to condemn the Syrian regime for its ongoing military crackdown against civilians.
Speaking on Friday, French Foreign Minister Alain Juppe said that tougher sanctions were needed on Syria and that France was ready to work together with the Syrian opposition.
