Meanwhile, Syria has dismissed allegations that it intends to use chemical weapons to end the unrest, stressing that it will never use weapons of mass destruction against its own people.
“In response to the statements of the US foreign minister, Syria confirms repeatedly that it will never, under any circumstances, use chemical weapons against its own people, if such weapons exist,” Syrian state television quoted a foreign ministry official as saying.
Syria has been the scene of unrest since March 2011, and many people, including large numbers of security forces, have lost their lives in the violence.
The Syrian government says foreign-backed “terrorists” are responsible for the killings, and that certain Western states, especially the United States, and their regional allies are fueling the turmoil.
On November 28, The New York Times said the US administration “is considering deeper intervention to help push President Bashar al-Assad from power.”
US President Barack Obama surmises that Damascus might have plans to use chemical weapons against foreign-backed militants in Syria.
On Monday, Obama, whose country is accused of being a key member of an international coalition attempting to destabilize Syria, warned Syrian President Bashar al-Assad not to use chemical weapons against the militants.
There would be consequences if Assad were to use these weapons, Obama warned, adding that "the world is watching" you.
"The use of chemical weapons is and would be totally unacceptable and if you make the tragic mistake of using these weapons there will be consequences and you will be held accountable," he stated.
Earlier in the day, US Secretary of State Hillary Clinton said that if the Syrian government uses the chemical weapons, it would mean that Damascus has crossed a US redline.
Commentators say the allegations are repeated attempts by the US to orchestrate an Iraq-like scenario against Syria.
