Defiant Assad claims government did not use chem weapons, vows to abide by agreement

Syrian President Bashar Assad, in an exclusive interview with Fox News, claimed he is fully committed to carrying out a plan to turn over and destroy his government's chemical weapons -- while continuing to deny responsibility for last month's deadly chemical weapons attack despite new evidence that officials say implicates the Assad regime. 

Assad acknowledged that his government has chemical weapons. "It's not a secret anymore," he said, referencing his government's decision to join the international Chemical Weapons Convention.
