U.S. envoy says important to de-escalate tension with Iran

The United States envoy on Iran, Brian Hook, said on Friday it was "important we do everything" to de-escalate tensions with Iran. "Our diplomacy does not give Iran the right to respond with military force, Iran needs to meet our diplomacy with diplomacy and not military force," he told a news conference in the Saudi capital Riyadh. "It's important we do everything we can to de-escalate."
