In an exclusive interview with ABC's Christiane Amanpour, Moammar Gadhafi's second son, Saif Gadhafi, said that Americans will "regret" their intervention in Libya. "One day, they will find that they were supporting the wrong side."

Gadhafi said that the American and coalition forces are supporting terrorists in Libya:

Simply the Americans and the other Western countries, you are supporting the terrorists and the armed militia. That's it...One day you will wake up and you made a big mistake with supporting these people. It’s like the WMD in Iraq. It’s another story

He said that he was "surprised" about the military intervention--and he went on to blame coalition forces for terrorizing Libyan citizens yesterday:

Yesterday, we were surprised that ... the Americans and the British and the French attacked Libya, attacked five cities. Terrorized people, and especially children, women, were so afraid yesterday...So it was big surprise that finally President Obama -- we thought he was a good man and friend of Arab world -- is bombing Libya

Will his father step down? "Step aside, why?"

Again, there is a big misunderstanding. The whole country is united against the armed militia and the terrorists. Simply the Americans and the other Western countries, you are supporting the terrorists and the armed militia. That's it
