DUBAI - Iranian authorities have arrested hundreds of people and executed half a dozen in a sweeping security crackdown that analysts say is aimed at exerting control after a brief but punishing war with Israel exposed Iran’s deep infiltration by Israeli intelligence.

"Khamenei's position is surely weakened," Arash Azizi, who unveiled an alleged plot against the supreme leader, told Newsweek.

Iran has raised the official death toll for its war with Israel, with official media reporting 935 people were killed in the country during the 12-day conflict.
