1 \ I published today on @news10 more details about the Mossad operation which discovered the facility in Tehran which PM Netanyahu called "the atomic warehouse". All the details from an Israeli official briefed on the operation are in this thread:
2 \ The Israeli official who spoke on condition of anonymity told me the Mossad discovered the "Atomic warehouse" in Tehran less than 3 months ago
3 \ The official said the Iranians stored in the warehouse nuclear materials they are not allowed to have without declaring it to the IAEA. The official added that after the facility raise suspicions the Mossad started a concentrated & focused monitoring effort around it
4 \ One if the results of the Mossad monitoring of the facility was this photo that Netanyahu presented at the UN yesterday 
5 \ The Mossad monitoring discovered the facility was under the responsibility of the Iranian ministry of defense and under the same department which was responsible for the past military nuclear work the Iranians did
6 \ This department, headed by Mohsen Fakhrizadeh, was also responsible for the facility that held the Iranian nuclear archives which were stolen by the Mossad earlier this year
7 \ The Israeli official told me that several weeks ago after the Mossad corroborated the information about the facility Israel briefed the U.S. government and intelligence community. Israel also briefed the IAEA which have never heard about this facility before
8 \ The official told me that a few weeks ago there was a meeting at the PM office to discuss whether to make the new intelligence public like Israel did with the Iranian nuclear archives. The decision was to disclose the new info in Netanyahu's UNGA speech
9 \ The official told me: "We had no other choice but to publish the new intelligence on the facility in Tehran because the goal was to push the IAEA to take action against this facility and other suspicious facilities in Iran
10 \ The official said Israel knows exactly what kind of materials the Iranians stored in the facility. He said it was "from the family of nuclear materials" which Iran is not supposed to have. The official added: "This is a much more serious case than the nuclear archives". END
