Iran said on Monday its security forces had thwarted a planned sabotage at the country's Fordow nuclear site by a network it accused Israel of recruiting, making arrests.

Iranian state television said an Israeli officer first contacted a neighbor of an employee of the uranium enrichment plant and managed to recruit them both after paying them in cash and digital currency.

Revolutionary Guards security agents were monitoring the network and were able to break it up before the sabotage could be carried out, arresting an unspecified number of people, the television said.

The state news agency IRNA said a new agency called Revolutionary Guards Nuclear Command, which it said had been set up to oversee defense and security matters at nuclear installations, was involved in the operation to stop the planned sabotage.

Iran has accused Israel of carrying out several attacks on facilities linked to its nuclear program and of killing its nuclear scientists over the past years. Israel has neither denied nor confirmed the allegations.

Iranian security agencies in the past have claimed arrests of spies and “terrorists” but have not produced any evidence and or follow up information about trials and possible sentences.

Israel confirmed reports late Monday that several websites, including its government site, were disrupted by a "broad cyberattack". The Iranian IRGC cyber army has attacked Israeli websites in the past.
