Australia’s foreign minister has said their intelligence shows ISIS has enough radioactive material to create a large “dirty” bomb.

Foreign Minister Julie Bishop told The Australian newspaper that ISIS has collected enough radioactive materials from hospitals and research centers in areas they have overtaken in the last few years.  She also said the group is now recruiting “highly trained professionals” to develop chemical weapons which could also be used to create “dirty” bombs.

“They seek to undermine and overthrow that order and as we have seen, are prepared to use any and all means, any and all forms of violence they can think of to advance their demented cause,” she said.  “That includes use of chemical weapons.”

“Chemical weapons often receive less public attention than nuclear and biological threats,” she also said, later adding, “However, toxic chemicals were, by far, the most widely used and proliferated weapons of mass destruction in the 20th century.”

Bishop is not the first international intelligence official to comment on the possibility of dirty bombs or nuclear weapons falling into the hands of ISIS.  Indian defense officials said that the terrorists are working to obtain a nuclear weapon from Pakistan.

Several intelligence officials are concerned about the approach of Ramadan, as ISIS has ramped up attacks in connection with the Muslim holy month.
