Mir also said that bin Laden has assigned a man named Adnan Al-Shukri Juma to carry out a new attack within the US which is intended to be larger than the 11 September, 2001 attacks. According to Mir, Adnan Jumaa has smuggled explosives and nuclear materials into the US through the Mexican border over the last two years and is hiding somewhere in America where the FBI has not been able to locate him.
