Stolen radioactive material that raised fears  last week that ISIS was building a radioactive “dirty bomb” has been found, Iraq announced Sunday. The “highly dangerous” material, which disappeared last November from a storage facility outside Basra belonging to a U.S. oilfield services company, was discovered dumped nine miles from Basra near a gas station in Zubair.

“A passer-by found the radioactive device dumped in Zubair and immediately informed security forces, which went with a special prevention radiation team and retrieved the device,” said Jabbar al-Saidi, of the Basra provincial council. Environmental ministry spokesman Ameer Ali said the device was not damaged and there were no concerns about radiation.

How and why the device and its dangerous contents ended up in Zubair is unknown.

Although it appears in this case radioactive material did not end up in the hands of ISIS, the danger of the terrorist group using a radioactive dirty bomb has not passed. According to the Australian newspaper The Independent, Australian intelligence officials concluded last summer that ISIS had already collected enough radioactive material to build such a weapon.
