The Cuban authorities were prompt to deploy helicopters which dropped a huge amount of water on the fire and that resulted in the entire area getting enveloped in a thick black smoke.

Some of the injured were taken to Calixto García hospital in Havana, which has a prominent burn unit after most of the victims received first aid just outside the affected facility.

“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. “The city has a strong smell of sulphur.”
