The Arab League's committee on Syria is scheduled to meet later Sunday to review a report by its monitoring mission to the violence-stricken country, DPA reported.
The committee's meeting will be held hours before an Arab foreign ministers meeting that will discuss whether to extend by another month the mandate of the observer mission, which was sent to Syria last month to monitor implementation of a peace plan.
At least 96 people were killed on Saturday. The death toll includes 60 bodies found in the morgue in the northern province of Idlib.
News coming out of Syria cannot be independently verified as journalists are banned from reporting freely from inside the country.
The Syrian opposition, which says the mission was manipulated by the regime and provided a diplomatic cover for the Syrian government to pursue a crackdown on rebels and protesters, is preparing its own report on the violence.
The opposition believes the Arab League report will be skewed in favour of the government.
At least 5,400 people have been killed in the government crackdown on protesters, who have been calling for the ouster of President Bashar al-Assad since mid-March.
