Omar Ossama bin Laden, 29, the al-Qaeda leader’s fourth-eldest son, said he had no idea that his brothers and sisters were still alive until they called him in November. They told him how they had fled Afghanistan just before the 9/11 attacks and walked to the Iranian border. They were taken to a walled compound outside Tehran where guards said they were not allowed to leave “for their own safety”. The eldest of the children, Saad, was 20 at the time, Ossman 17, Muhammad 15, Fatma 14, Hamza 12, Iman 9, and Bakr, 7.
There had been speculation that Muhammad was second in command of al-Qaeda and that Saad also instigated and plotted terrorist attacks until he was killed about 18 months ago by an American drone. The relatives, however, said that Muhammad is still living in the compound and that Saad ran away less than a year ago in an attempt to find his mother.
