US stock futures tumbled sharply after President Trump declared the Iran deal 'over', triggering a 6 percent plus surge in crude prices with Brent and WTI rallying on fears of tighter supply. Nasdaq futures hit a four-week low, energy stocks like Chevron and Exxon rose in premarket trade, while airline and cruise operators declined on fuel cost concerns.
