The UN’s nuclear watchdog has reported that two and a half tonnes of uranium had gone missing from a plant in Libya.
The International Atomic Energy Agency (IAEA) issued the warning following a visit to the unnamed facility by its inspectors earlier this week.
According to the IAEA, they discovered that ten drums carrying uranium ore had vanished.
There are concerns about uranium being a radioactive risk, as well as nuclear security problems.
In a statement, the IAEA said it would conduct further actions to clarify the circumstances surrounding the removal of the radioactive material and its current position.
It is unknown when the uranium vanished. Inspectors reportedly wanted to visit the site last year, but the trip was canceled due to fighting between various Libyan groups.
According to the IAEA, the uranium storage location was not on government-controlled territory.
Libya has been divided into opposing political and military factions since the overthrow of former tyrant Colonel Muammar Gaddafi in 2011.
It is presently divided between an interim government in Tripoli and another in the east.
