In an interview with The Associated Press in Damascus, Syrian Deputy Foreign Minister Faisal Mikdad said airstrikes or other action against Syria would also trigger "chaos" and threaten worldwide peace and security.

United Nations chemical weapons investigators have returned to their Damascus hotel after visiting the scene of a suspected poison gas attack in Syria on Monday.

Secretary of State John Kerry on Monday called Syria’s use of chemical weapons “undeniable” and indicated that President Barack Obama is plotting action in the coming days.

Setting the stage for eventual military intervention, Kerry said in a statement from the State Department that what is happening on the ground in Syria “is real and it is compelling” and requires a response from the international community.
