Iran alleges UN inspector tested positive for explosives

Iran alleged Thursday that the U.N. inspector it blocked from a nuclear site last week tested positive for suspected traces of explosive nitrates. The U.N.'s nuclear watchdog, the International Atomic Energy Agency, did not immediately comment.

The allegation made by Iranian representative Kazem Gharib Abadi came as Iran injected uranium gas into centrifuges at its underground Fordo nuclear complex early Thursday, taking its most-significant step away from its 2015 nuclear deal with world powers.

These latest steps by Iran put additional pressure on Europe to offer Tehran a way to sell its crude oil abroad despite the U.S. sanctions imposed on the country since President Donald Trump unilaterally withdrew America from the nuclear deal over a year ago.

The incident happened at Iran's Natanz nuclear facility, which includes the majority of the centrifuges now enriching uranium in the country. The entrance of Natanz includes equipment to check for traces of nitrates, Abadi said.

"The detector's alarm went off and it was signaling to a specific person," he said.

"They have repeated this procedure again and again, and unfortunately, the results were the same all the way for only that specific inspector." As they waited for a female employee to search the inspector, the woman went off to the bathroom. Abadi alleged when she came back, she no longer tested positive. He said the team took samples from the bathroom, as well as seized her handbag.

Abadi said he hoped further tests by Iran and the IAEA would explain what happened. Iran's nuclear industry has been targeted by sabotage and its scientists assassinated in the past.

"Needless to say that Iran, like all other members of the agency, cannot condone any behavior or action which may be against the safety and security of its nuclear installations, especially ... considering the past sabotage attempts in its nuclear facilities," Abadi said.

This marks the first known time of Iran blocking an inspector amid the tensions. Nitrates are a common fertilizer. However, when mixed with proper amounts of fuel, the material can become an explosive as powerful as TNT. Swab tests, common at airports and other secure facilities, can detect its presence on the skin or objects.

Jackie Wolcott, the U.S. representative to the IAEA, earlier called the inspector's rejection an "outrageous provocation." "All board members need to make clear now and going forward that such actions are completely unacceptable, will not be tolerated, and must have consequences," Wolcott said in remarks released to journalists. "If the
Experts have suggested that the limits imposed under the 2015 deal, when obeyed, meant that Iran would need a year to gather enough material to build a nuclear weapon if it chose to do so a time known as a "breakout period."
