Saudi oil tankers sabotaged in Persian Gulf

Explosions were reported on two of the ships offshore of the United Arab Emirates port of Fujairah. Tensions have risen in the oil-rich region in recent weeks amid the deployment of a growing number of United States warships to the Middle East due to deteriorating relations with Iran. The US has deployed warships to the region in recent days as tensions ramp up between the US and Iran. The BBC's security correspondent Frank Gardner talks through the impacts with Susie Ferguson.
