Tunisia’s National Guard spokesman told Mosaique FM radio that reports of a drone attack on the flotilla “have no basis in truth”, Reuters reported.
He added that an initial inspection indicated the explosion originated inside the vessel.
In a series of videos published to their Instagram, spokespeople for the flotilla said an “incendiary device” caused a fire onboard the vessel, which the crew was able to extinguish.
The picture on the bbc site is a still from the footage as well. You watch the burning object hit the deck, then they placed the image of it on the deck… so they had to know the object came from above.
