ISRAEL’s nighttime mission earlier this year to steal nuclear secrets from an Iranian warehouse has been detailed by Israeli officials speaking to the New York Times, in an article published on Sunday.

The mission resulted in Israel obtaining documents suggesting Iran defied the spirit of its 2015 accord on its nuclear program with the United States, European powers, Russia and China.

The six-and-a-half-hour mission included two dozen spies, sophisticated alarm systems, metal safes and high-powered gadgets that targeted a warehouse in Tehran, according to the report.

Mossad agents reportedly knew that the warehouse had a trove of damning data and monitored the location for a year, learning how they could crack the best part of 32 Iranian-built safes.

At 10.30 p.m. on Jan. 31, a team of two dozen Mossad agents — mostly Iranian double spies — breached the warehouse by tampering with the alarm system to make it appear functional even as they had their run of the place.

As there were no guards stationed outside the warehouse at night, “to keep the site’s profile low,” the agents were able to tear through the safes with special torches that reached a 3,600 degrees.

They managed to leave with about 50,000 pages and 163 compact discs’ worth of intelligence and pulled out at 5 a.m., before the warehouse guards resumed their posts at 7 a.m.

In April, Israeli Prime Minister Benjamin Netanyahu presented the findings after Israel had combed through the documents.

Netanyahu said that the intelligence proved Iran had been holding onto information from its ostensibly defunct nuclear research program, signaling its aspiration to resume its research.

Iranians have since claimed that the Israeli haul is fabricated, but US and British officials validated it. Another report, from the Washington Post, said that Iran was on the verge of acquiring "key bomb-making technologies" when the program, code-named Project Amad, was halted some 15 years ago. — Al Arabiya English
