Attack on oil stations 'cowardly' - Saudi Arabia

Two days after Saudi oil tankers were sabotaged off the coast of the United Arab Emirates, two oil pumping stations have now been attacked in what the kingdom has called a "cowardly" act of terrorism. About a fifth of the world's oil passes through the area and oil prices rose following the incident. The attacks are putting pressure on already strained relations in the area and heightened tensions between the US and Iran. The BBC's security correspondent is Frank Gardner. He talks to Susie Ferguson.
