Two Saudi oil tankers were the targets of a “sabotage attack” off the United Arab Emirates (UAE) on Sunday, Saudi Arabia’s energy minister says. The incident near Fujairah port, in the Gulf just outside the Strait of Hormuz, caused “significant damage” to the ships, according to Khalid al-Falih. The UAE said four ships were targeted, but that there were no casualties. Iran, which borders the strait, called the incident “worrisome and dreadful” and called for a full investigation. Tensions are high in the region, through which about a fifth of oil that is consumed globally passes.
