Opposition fighters across Syria are preparing to launch attacks that exploit anticipated US-led military strikes, a rebel commander has said.
But Qassim Saadeddine, a former Syrian army colonel and spokesman for the rebels' Supreme Military Council, added that there are no plans to coordinate with Western forces.
He told Reuters: "The hope is to take advantage when some areas are weakened by any strikes.
"We ordered some groups to prepare in each province, to ready their fighters for when the strike happens."
On Friday, the US it was considering a limited response to a "brutal and flagrant" chemical weapons attack by the Syrian regime it says killed more than 1,400 people in Damascus.
US Ambassador Samantha Power has said that chemical weapons "should never be used" again, after a US intelligence report says at least 1429 people including 426 children were killed in the attack.
The Obama administration released a declassified intelligence report that links the Syrian regime to chemical weapons use today.
President Obama tonight insisted he was undecided about the prospect of US military action but said any action would be "limited"
Syria has denied charges by US Secretary of State John Kerry that it uses chemical weapons, adding that "what he said was lies" and baseless.
Syria's foreign minister said Kerry's claims are a "desperate attempt" to justify "potential aggression".
US Secretary of State John Kerry has emphatically underlined the evidence America claims points to Assad's regime attacking its own people with chemical weapons on August 21.
He said: "Our intelligence community has carefully reviewed and re-reviewed information regarding this attack, and I will tell you it has done so more than mindful of the Iraq experience - we will not repeat that moment."
A map to accompany a US Government report shows the areas reportedly affected by a chemical weapons attack in the suburbs of Damascus in Syria.
A US report said it had intelligence which led it to believe that "Syrian chemical weapons personnel were preparing chemical munitions prior to the attack".
A US intelligence report said it assessed with "high confidence" that the Syrian Government carried out the chemical weapons attack in the suburbs of Damascus earlier this month.
Secretary of State John Kerry described Syrian President Assad a "thug and a murderer" and the world had a choice of what to do.
Mr Kerry told a press conference: "Some cite the risk of doing things, but we need to ask what is the risk of doing nothing? It matters because if we choose to live in a world where a thug and a murderer like Bashar al-Assad can gas thousands of his own people with impunity.
"Even after the US and our allies said no and then the world does nothing about it - There will be no end to the test of our resolve."
Secretary of State John Kerry said the UN inspectors could not tell the US anything it did not already know about the chemical weapons attack in Syria on August 21.
A intelligence report also said it was "highly unlikely" the Syrian opposition executed the attack.
