Exhaustive investigations into the deadly explosion of the Sejil-2 ballistic missile at the Revolutionary Guards (IRGC) Alghadir base last Saturday, Nov. 12 point increasingly to a technical fault caused by the computer system controlling the missile and not the missile itself. The head of Iran's ballistic missile program Maj. Gen. Hassan Moghaddam was among the 36 officers killed in the blast. DEBKAfile: The IRGC is investigating the possible Stuxnet virus infection of this computer system as the cause of the explosion.
