After burning for five days, the massive blaze has been subdued.

On Friday, a lightning strike at the Matanzas super tanker port in Cuba sparked off a massive oil fire. The fire swiftly spread to other tanks over the course of several days, leading to explosions, power outages, and copious smoke. The fire has been declared the worst one ever seen on Cuban soil.

Today, after five days of firefighting efforts, Cuban firefighters have successfully subdued the blaze, though significant damage has already been done to the area. Roughly 40% of the Matanzas port was destroyed, and as Matanzas is the main fuel storage area for all of Cuba, this will likely lead to severe power complications throughout the country for the foreseeable future.

“The situation is going to be more difficult. If the thermoelectric plants are supplied with that oil, we are going to have the whole world affected, it is electricity and it affects everything,” Firefighter Rafael Perez Garriga told Reuters.

Authorities have said that no oil leaked out into the nearby Matanzas Bay. However, due to the lingering clouds of dense smoke, nearby communities have been advised to don face masks and be on the lookout for acid rain caused by the looming smoke. As of Tuesday, one firefighter was killed in action when one of the tanks exploded, while 14 Firefighters are still missing. Five firefighters have been transported to local hospitals in critical condition.
