Workers of the Cuba Oil Union, known by the Spanish acronym CUPET, watch a huge rising plume of smoke from the Matanzas Supertanker Base, as firefighters work to quell a blaze which began during a thunderstorm the night before, in Matazanas, Cuba, Saturday, Aug. 6, 2022. Cuban authorities say lightning struck a crude oil storage tank at the base, causing a fire that led to four explosions which injured more than 50 people. (AP Photo/Ramon Espinosa)
