Russia contributing to potential Syria civil war - US
UN Secretary General Ban Ki-moon has repeated a warning that Syria could be moving towards "catastrophic" civil war, in the wake of the Houla massacre.
Rebel commanders are split on whether to abandon a ceasefire if Syrian forces do not withdraw to barracks.
The FSA's Colonel Qassim Saadeddine in Homs said that if there was no government response by Friday lunchtime the FSA would consider itself "no longer bound" by the plan.
But the FSA head, General Riyad Asaad, later denied the deadline existed.
Instead, he urged peace envoy Kofi Annan to issue a statement declaring his peace plan to have failed.
Taldou, Houla region
- The region of Houla, in the west of Syria, comprises several villages and small towns
- The village of Taldou lies around 2km south-west of the main town, also called Houla
- The area is in the province of Homs, which has seen heavy fighting in recent months
- Houla's villages are predominantly Sunni Muslim, but the region is ringed by a number of Alawite villages - the sect of the Syrian president Bashar al-Assad
But Colonel Asaad, speaking to al-Jazeera by phone from Turkey, insisted the FSA was "committed to the Kofi Annan plan and committed to international resolutions and implementing this plan".
"There is no deadline; however, we hope that Kofi Annan will issue a statement to announce the failure of this plan," he said.
The UN Human Rights Council will hold a special session on Syria on Friday looking into the killings, officials said.
As many as 15,000 people have been killed since the revolt against the rule of President Bashar al-Assad began in March of last year.
