Iran's top security body said Saturday that action by Britain, France and Germany to reimpose UN sanctions will "effectively suspend" its cooperation with the UN nuclear watchdog.

"Despite the foreign ministry's cooperation with the (International Atomic Energy) Agency and the presentation of plans to resolve the issue, the actions of European countries will effectively suspend the path of cooperation with the agency," the Supreme National Security Council said in a televised statement.

The announcement comes after the Security Council voted on Friday to reimpose frozen UN sanctions after the European governments activated the "snapback" mechanism in a decade-old nuclear agreement accusing Iran of non-compliance.
