(CNBC) WASHINGTON – Secretary of State Mike Pompeo on Thursday blamed Iran for attacks earlier in the day on oil tankers in the Gulf of Oman near Iran and the Strait of Hormuz, a vital shipping route through which much of the world’s oil passes.
“Iran is lashing out because the regime wants our successful maximum pressure campaign lifted,” Pompeo said without citing specific evidence as to why Tehran was responsible. “No economic sanctions entitle the Islamic Republic to attack innocent civilians, disrupt global oil markets and engage in nuclear blackmail.”
Oil prices rose as much as 4% on Thursday on renewed fears of conflict in the Middle East after a series of strikes last month. Crude futures briefly jumped back above 3% after Pompeo accused Tehran.
Meanwhile, the Pentagon said in a statement that the U.S. Navy’s Fifth Fleet received two separate distress calls from the oil tankers shortly after the attacks.
“USS Bainbridge was operating in the vicinity and provided immediate assistance to the M/V Kokuka Courageous. Twenty-one mariners from the M/V Kokuka Courageous, who abandoned ship, are currently aboard USS Bainbridge. A Navy P-8 is also providing support,” wrote Lt. Col Earl Brown, spokesman for U.S. Central Command, in a statement.
Last month, the Pentagon announced it was sending additional U.S. troops, drones and fighter jets to the Middle East amid increasing tensions between the Washington and Tehran. Defense officials at the Pentagon said they had credible intelligence that Iran and its proxies are planning to attack American forces in Iraq.
“The deployment will include approximately 1,500 U.S. military personnel and consist of a Patriot battalion to defend against missile threats, additional intelligence, surveillance, and reconnaissance aircraft, an engineer element to provide force protection improvements throughout the region and a fighter aircraft squadron to provide additional deterrence and depth to our aviation response options,” acting Secretary of Defense Patrick Shanahan wrote in a May 24 statement.
The movement of additional U.S. forces to the region is the Trump administration’s latest effort to pressure Tehran over its support for weapons proliferation and extremist groups in the Middle East.
Last month, Trump ordered new sanctions placed on Iranian metals, Tehran’s largest non-petroleum-related source of export revenue. The U.S. also took aim at Iranian oil by effectively ordering countries worldwide to stop buying Tehran’s oil or face sanctions of their own.
Additionally, the U.S. designated Iran’s Revolutionary Guard as a terrorist group. Iran responded with threats to close the Strait of Hormuz, where about a third of the world’s oil export vessels pass. The U.S. then announced it was expediting the deployment of a carrier strike group equipped with bomber aircraft to the region.
Tehran announced it was relaxing some restrictions on its nuclear program but would not violate a 2015 accord with Russia, China, Britain, France, Germany and the United States. Iran had agreed to the 2015 limits on its disputed nuclear program in return for sanctions relief.
A year ago Trump withdrew the U.S. from the Joint Comprehensive Plan of Action, calling it a “horrible, one-sided” deal.
