The decision took 36 hours of frantic discussions Syria is ready to allow a senior Arab League mission into the country to try to help end the bloodshed, sources have told news agencies. 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.
