Syrian President Bashar Assad, during an interview that aired Monday morning, threatened “repercussions” from any American attack on Syria.

The Syrian leader, speaking with CBS News, said the U.S. can expect “every action” if America strikes. He suggested retaliation could come from the opposition, as well as his own government and its allies.

“You should expect everything,” Assad said. Asked to elaborate, he added: “You should expect everything. Not necessarily from the government. … You have different parties, you have different factions, you have different ideology.”

Asked specifically if the attack could trigger more chemical warfare, Assad suggested the rebels would be the ones who would use them. He said that outcome depends on whether “terrorist” rebels possess those weapons, adding: “It could happen.”
