Three European Union nations plan to propose a resolution to condemn Syria at the United Nations General Assembly session on Thursday.
Germany, Britain and France are behind the measure that strongly condemns the Assad regime's human rights violations and calls for an immediate end to the government violence against civilians in the country.
The move came following Wednesday's formal confirmation of the suspension by the Arab League of Syria's membership in the regional body.
The Arab League issued a three-day ultimatum to Syrian President Bashar al-Assad to end the violence and accept a delegation of observers, or face economic sanctions.
A draft of the U.N. resolution is being circulated among members of the General Assembly's human rights committee.
A vote on the non-binding measure to condemn the Syrian government for its nine months of violence against civilian protesters is expected to be scheduled for Tuesday.
Sources told the Reuters news agency Wednesday on condition of anonymity that Saudi Arabia, Jordan, Qatar, Morocco and Kuwait are all considering co-sponsoring the measure.
The embassies of several Arab nations were attacked by angry mobs of Assad loyalists last weekend and again on Wednesday in response to the Arab League suspension.
The United Nations has estimated that at least 3,500 people have died in the violence since March. But human rights organizations place the death toll much higher, claiming more than 4,500 people have been killed.
More then 300 people have died in the Syrian government crackdowns so far this month alone.
