(CBS News) Libyans reacted with shock, sadness and a sense of shame to the possible terror 안동출장만남 attack that killed a U.S. ambassador and three other Americans, CBS News correspondent Charlie D’Agata reported on “CBS This Morning” Thursday from the city where the attack took place.

In the wake of Tuesday’s killings of U.S. Ambassador Christopher Stevens, Foreign Service Officer Sean Smith and two Marines at the U.S. Consulate in the port city of Benghazi, Libyans held a pro-American rally Wednesday.

“When you talk to Libyans here you hear the same thing: Everybody is heartbroken. They’re saddened, they’re shocked by what’s happened,” D’Agata told Norah O’Donnell and Charlie Rose. “They say that they’re ashamed of what’s happened. They say the ambassador is a personal friend to the Libyans.”

Libyan officials told D’Agata that they would work with the FBI team investigating the attack. U.S. officials increasingly believe that the attackers may have had terrorist links and were not solely members of a spontaneous mob demonstrating at the consulate against an online video ridiculing Islam’s Prophet Muhammad.
