Israel's prime minister on Monday unveiled what he said was a previously undisclosed Iranian nuclear weapons site, further escalating a showdown between the two enemy countries.
Benjamin Netanyahu's announcement came as the UN nuclear watchdog held a meeting in Vienna, where he's hoping the agency will take tougher action against Iran.
It also came in the final stages of Israeli national elections, drawing criticism from opponents that the sudden press conference was a campaign stunt.
Speaking to reporters, Netanyahu said Israel discovered the facility, located in the central Iranian town of Abadeh, by using information gathered in a trove of documents Israeli agents stole from an Iranian warehouse and made public early last year.
"Iran conducted experiments to develop nuclear weapons," Netanyahu said.
He provided no details or evidence of what those experiments were, but he showed off two satellite photos. The first, taken in June, showed the facility intact.
The second, taken in July, showed parts of the building had been destroyed, in what he said was an Iranian cover-up after Israel discovered the facility.
"This is what I have to say to the tyrants of Tehran," he said.
"Israel knows what you're doing, Israel knows when you're doing it, and Israel knows where you're doing it."
One of his main rivals, Blue and White party candidate Yair Lapid, accused Netanyahu on Twitter of using the Iran expos as "election propaganda at the expense of security."
