Energy ministers from OPEC and its allies meet to discuss prices and production cuts, in Jiddah, Saudi Arabia, Sunday, May 19, 2019. The meeting takes place as tensions flare in the Persian Gulf after the U.S. ordered bombers and an aircraft carrier to the region over an unexplained threat they perceive from Iran, which comes a year after the U.S. unilaterally pulled out of Tehran's nuclear deal with world powers and reimposed sanctions on Iranian oil.
