The Arab League has called an emergency meeting on Syria's failure to implement its peace plan, as forces reportedly killed at least 12 demonstrators after prayers on one of Islam's holiest days.
The announcement that Arab foreign ministers would hold the gathering came on the fourth straight day of violence since Syria agreed to the league's peace blueprint aimed at ending eight months of bloodshed.
The Arab League said a meeting was called for next Saturday because of "the continuation of violence and because the Syrian government did not implement its commitments in the Arab plan to resolve the Syrian crisis".
Qatari Prime Minister Sheikh Hamad bin Jassem al-Thani, chair of an Arab panel on the crisis, has said "if Syria does not respect its commitments, the ministerial committee will meet again and take the necessary decisions".
A human rights group said that security forces killed at least 12 civilians as anti-regime demonstrations were staged across Syria today, the first day of the Eid al-Adha feast marking the end of the hajj pilgrimage.
French Foreign Minister Alain Juppe said the continued killings made it clear that President Bashar al-Assad's regime had no intention of ending its bloody bid to crush dissent.
Nine of the civilians were killed in Homs, the flashpoint central city where protests against Mr Assad's rule were held in most districts despite a weeks-long military crackdown.
Most of the deaths occurred in the Baba Amro neighbourhood of Homs, where clashes have raged for days, the Syrian Observatory for Human Rights said in a statement received in Nicosia.
Security forces also shot dead two civilians in the city of Hama, which lies further to the north, and another in Idlib province, near the border with Turkey.
The latest deaths bring to at least 60 the number of people killed since Mr Assad's government signed on to the Arab League peace plan on 2 November.
The Arab roadmap calls for an end to violence, the release of those detained, the withdrawal of the army from urban areas and free movement for observers and the media, as well as talks between the regime and opposition.
As a first step, Syria on yesterday said it had released more than 550 people who were arrested during anti-regime protests, to mark the Eid al-Adha feast.
But the Syrian Observatory said detainees in prisons across Syria had today begun hunger strikes in protest at the authorities "who are not keeping their promises of freedom".
The French foreign minister said it was now clear there was "nothing more to expect" from Mr Assad's regime in terms of honouring its commitments under the Arab peace plan.
"Bashar al-Assad accepts the Arab League peace plan and the next day he massacres dozens more people in the streets," Mr Juppe told Europe 1 radio.
Arab League chief Nabil al-Arabi had warned the failure of the deal would be "disastrous" for Syria and the region and demanded an immediate end to the bloodshed.
The United Nations estimates that more than 3,000 people have been killed in a brutal crackdown since anti-regime protests erupted in mid-March.
