“Documents released by Wikileaks disclose that al-Qaeda is on the verge of manufacturing a nuclear weapon.
At a Nato meeting in January 2009, security chiefs briefed member states that al-Qaida was plotting a program of “dirty radioactive IEDs”, makeshift nuclear roadside bombs that could be used against British troops in Afghanistan.
As well as causing a large explosion, a “dirty bomb” attack would contaminate the area for many years.
Freight trains were found to be carrying weapons-grade nuclear material across the Kazakhstan-Russia border, highly enriched uranium was transported across Uganda by bus, and a “small time hustler” in Lisbon offered to sell radioactive plates stolen from Chernobyl.
In one incident in September 2009, two employees at the Rossing Uranium Mine in Namibia smuggled almost half a ton of uranium concentrate powder – yellowcake – out of the compound in plastic bags.”
