This is the first time an Iranian official has explicitly confirmed the extent of Mossad's infiltration into Iran's nuclear program.

Israel supplied Iran with centrifuge platforms containing explosives for its nuclear enrichment program in an act of sabotage.

Israeli intelligence agencies planted explosives inside equipment destined for Iran’s nuclear programme, the Islamic Republic’s vice president has said.

France has underlined the urgency of a diplomatic solution in response to Iran's advancing nuclear programme as a second round of talks get underway in Geneva, ahead of next week's inauguration of Donald Trump as US president.

Iran's leader made the claim less than a week before the president-elect returns to the White House. In his first term, Trump took a tough line on Iran.
