Israeli Mossad agents seized Iran’s secret nuclear weapons files in an overnight raid on a warehouse in Tehran and returned to Israel with them that same night, the New York Times reported on Monday.

An Israeli official, who asked to remain anonymous, told the American newspaper that the Mossad had been monitoring the top-secret warehouse since February 2016. The raid took place in January 2017, and US President Donald Trump was reportedly informed of the operation by Mossad chief Yossi Cohen, who was in Washington around the same time of the raid.

According to the source, the announcement of the impressive intelligence achievement was delayed because it took the Mossad a while to translate the documents from Persian and analyze them.

Meanwhile, Hadashot news reported that a former senior intelligence official claimed that Iran could have used the documents in the future to develop a nuclear weapon once the nuclear deal expires. In addition, a top Israeli official said that it appears Trump has already made up his mind about the future of the nuclear deal and therefore Israeli Prime Minister Benjamin Netanyahu’s announcement last night was orchestrated to support the American leader’s position, not to pressure him into making a certain decision.

Watch: Netanyahu makes Iran’s nuclear files public

Last night, Netanyahu addressed the nation and the world from the IDF headquarters in Tel Aviv to reveal “Iran’s secret nuclear files.” Speaking in English, Netanyahu showed the world Israel’s “great intelligence achievement.”

Netanyahu said that in the operation, the agents obtained tens of thousands of pages and 55,000 files on over 100 CDs that contain “incriminating documents, incriminating charts, incriminating presentations, incriminating blueprints, incriminating photos, incriminating videos and more.”
