At least 32 have been killed in violence.
Syrian activists, however, doubt Arab monitors are getting the access they need to be able to give a fair assessment of the violence that the UN estimates has left more than 5,000 people.
A member of the observer team told Al Jazeera the situation in Syria was “very dangerous”.
The official, who declined to be named, said there was constant shelling in the city of Homs with some areas under control of the Free Syrian Army, an umbrella group of armed anti-government fighters.
The source said he believed the Arab League mission was certainly going to fail.
