Arab League foreign ministers are meeting in Cairo on Sunday to assess the findings their mission in Syria.
The observer mission, sent by the League to oversee a peace plan for the country in December, has been heavily criticized by the Syrian opposition for not doing enough to stop the violence.
League ministers are expected to discuss whether to ask for help from the UN human rights experts and also look whether the observers can operate more independently of Syrian authorities, the BBC reported.
More than 5,000 people are believed to have been killed since protests against President Bashar al-Assad began last March.
According to the London-based Observatory for Human Rights, at least 11 Syrian soldiers were killed in fighting with deserters in Deraa province on Sunday.
Earlier on Sunday, a Russian naval flotilla docked in the Syrian port of Tartus, in what the official Sana news agency called a “show of solidarity with the Syrian people.”
The group, led by an aircraft carrier, will spend six days in Tartus, where Russia has had a naval base since Soviet times, Sana reported.
