The French and US Presidents want to send Assad a "strong message" after a chemical attack in Syria left more than 1,000 dead, the French presidency said according to AFP.
Earlier a US intelligence report revealed that it assessed with "high confidence" that the Syrian regime carried out the attacks in the suburbs of Damascus earlier this month.
The US is considering a "limited act" in response to the alleged use of chemical weapons by the Syrian army, but how will Assad respond?
Will America go it alone in Syria after the Government's defeat in the Commons last night? The answer is yes. Emphatically yes.
As the West wakes up to another day, it is not just Prime Minister David Cameron who has a Syria problem - so does President Barack Obama.
