Saif al-Arab, 29, and three of Qaddafi's grandchildren, all reported to be under 12, died at their villa in the Bab al-Aziziya compound. The Libyan leader himself and his wife were in the villa at the time, Ibrahim said, but were unharmed.
The airstrike came after NATO rejected a cease-fire offer from Qaddafi yesterday, saying his forces must stop their attacks on civilians before it considers any truce.
Ibrahim said the strike was a “direct operation to assassinate” Qaddafi, and it "is not permitted by international law. It is not permitted by any moral code or principle.” However, Lieutenant-General Charles Bouchard, who commands the alliance’s operation, said in a statement on NATO’s website that "We do not target individuals."
