Bashar al-Assad: If Bombs Fall, 'You Should Expect Everything'

Tensions are running high as the U.S. prepares to decide whether or not it will follow through with military action against Syria, but Syrian President Bashar al-Assad is still denying that he ever used chemical weapons against his own people.

In an interview with CBS's Charlie Rose, Assad said there is "not a single shred of evidence" that the Syrian government used chemical weapons, despite what the White House and other officials have said.

"We're not sure that anything happened," Assad said. "Our soldiers in another area were attacked chemically, our soldiers. They went to the hospital as casualties because of chemical weapons. But in the area where they said the government used chemical weapons, we only had video and we only have pictures and allegations. We're not there."

Assad went on to say he expected the Obama administration to be different than George W. Bush's.

"That reminds me, about what Kerry said, about the big lie that Colin Powell said in front of the world on satellites about the WMD in Iraq before going to war when he said, 'This is our evidence.' Actually, he gave false evidence. In this case, Kerry didn't even present any evidence."

Rose suggested evidence was presented to Congress, but Assad condemned that notion.

"If they had it, they would have presented it to you," he told Rose. "You're a reporter, get this evidence and show it to the public."

Assad said if bombs do fall in Syria, "You should expect everything. You should expect everything. Not necessarily from the government. It's not only the government; [it's] not the only player in this region."
