Isis’s dirty bomb: Jihadists have seized ‘enough radioactive material to build their first WMD’

The Isis militant group has seized enough radioactive material from government facilities to suggest it has the capacity to build a large and devastating “dirty” bomb, according to Australian intelligence reports.

Isis declared its ambition to develop weapons of mass destruction in the most recent edition of its propaganda magazine Dabiq, and Indian defence officials have previously warned of the possibility the militants could acquire a nuclear weapon from Pakistan.
