That an American citizen had been killed by the CIA without trial drew criticism. American authorities quickly back-pedaled on their stories celebrating the death of Derwish, instead noting they had been unaware he was in the car which they said had been targeted for its other occupants, including Abu Ali al-Harithi, believed to have played some role in the USS "Cole" bombing. According to former FBI agent Ali Soufan, Derwish was al-Harithi's main assistant.
