A fire set off by a lightning strike at an oil storage facility raged uncontrolled Saturday in the city of Matanzas, where four explosions and flames injured nearly 80 people and left 17 firefighters missing, Cuban authorities said. Firefighters and other specialists were still trying to quell the blaze at the Matanzas Supertanker Base, where the fire began during a thunderstorm Friday night, the Ministry of Energy and Mines tweeted. The governmeht said later that it had asked for help from international experts in “friendly countries” with experience in the oil sector. The official Cuban News Agency said lightning hit one tank, starting a fire, and the blaze later spread to a second tank. As military helicopters flew overhead dropping water on the blaze, dense column of black smoke billowed from the facility and spread westward more than 100 kilometers (62 miles) toward Havana. The Facebook page of the provincial government of Matanzas said the number of injured had reached 77, while 17 people were missing. The Presidency of the Republic said the 17 were “firefighters who were in the nearest area trying to prevent the spread.” The accident comes as Cuba struggles with fuel shortages. There was no immediate word on how much oil had burned or was in danger at the storage facility, which has eight giant tanks that hold oil used to fuel electricity generating plants. “I was in the gym when I felt the first explosion. A column of smoke and terrible fire rose through the skies,” resident Adiel Gonzalez told The Associated Press by phone. “The city has a strong smell of sulfur.” Authorities said the Dubrocq neighborhood closest to the fire was evacuated, while Gonzalez added that some people decided to leave the Versailles district, which is a little farther from the tank farm. Many ambulances, police and fire engines were seen in the streets of Matanzas, a city with about 140,000 inhabitants that is on Matnzas Bay. Cuban President Miguel Diaz-Canel traveled to the area of the fire early Saturday, officials said. Local meteorologist Elier Pila showed satellite images of the area with a dense plume of black smoke moving from the point of the fire westward and reaching east to Havana. “That plume can be close to 150 kilometers long,” Pila wrote on his Twitter account.

The new head of Cuba's legendary National Ballet says she hopes to renew the institution after the death of long-time director Alicia Alonso by introducing new choreography and appearances by dancers who have emigrated to other companies.
