Dozens of people accused of sharing sensitive information with Israel have been arrested in several areas of Iran, local media reported on Sunday.
According to Tasnim news agency, 20 people were arrested in northwestern Iran on accusations of sending location details on Iran's military and security assets to Israel.
In northeastern Iran, 10 people were arrested, with some accused of collecting information on sensitive locations and economic infrastructure.
A provincial branch of the Revolutionary Guards' intelligence organisation said, 'As the Zionist enemy (Israel) and the US are attempting to invade Iran, they simultaneously activate mercenaries and spies to carry out riots as the next step.'
Israel has begun targeting security checkpoints based on tip-offs from informants on the ground, representing a new phase of its assault on Iran, a source briefed on Israel's military strategy told Reuters this week.
