Haiti’s Civil Protection Agency didn't immediately return a message seeking comment on Monday.
The explosion occurred Saturday in the southern coastal city of Miragoane after the truck flipped over.
In 2021, 75 people were killed in the northern city of Cap-Haitien, when another fuel truck overturned and unleashed a fireball that swept through several homes and businesses. Some of those killed were onlookers who had rushed to the truck to try and scoop up fuel.
