Nuclear facility

Yossi Cohen gave details about the theft of Iran's nuclear archive.

The warehouse raid in 2018 ferried tens of thousands of documents out of the country to Israel.

He also hinted at Israeli involvement in the destruction of Iran's nuclear facility at Natanz, and the assassination of a nuclear scientist.

Cohen retired as the head of Mossad last week.

He spoke to journalist Ilan Dayan on Channel 12's Uvda documentary programme, which was broadcast on Israeli television on Thursday night.

Though the official said the drills are not aimed particularly at North Korea, the announcement comes less than two weeks after North Korea claimed to have successfully tested a nuclear warhead -- its second nuclear test this year and fifth one ever.

The US and South Korea will also simulate what to do in the event of a sudden missile attack.
