The White House on Thursday again evaded direct questions about whether chemical weapons have been deployed in Syria. White House press secretary Jay Carney would not deny definitively that chemical weapons were used in the city of Homs, despite claims made in a recent classified State Department cable that such weapons had been used. Carney referred to the information in the cable as “anecdotal” and said that the State Department could not independently corroborate the information in the cable, which originated from a third-party source on the ground in Syria.
