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.

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.

Iran on Wednesday officially suspended its cooperation with the UN nuclear watchdog, a move triggered by the unprecedented Israeli and US strikes on its nuclear facilities.

The source also disputed suggestions that Iran had time to move enriched uranium stockpiles out of its nuclear facilities before the strikes. "It was stockpiled at Isfahan, Natanz and Fordow and it's now under the rubble," they said.

Iran is assessing the damage and lashing out over the American and Israeli airstrikes on its nuclear sites, though Tehran kept open the possibility Tuesday of resuming talks with Washington over its atomic program.
