Tunisian authorities claim they found no evidence of a hostile act and say the fire originated inside the Family Boat.

The Gaza-bound Global Sumud Flotilla (GSF) says a drone has struck its main ship in the Tunisian port of Sidi Bou Said, causing a fire, but that all its passengers and crew were safe.

A spokesman for the GSF blamed Israel for the incident, which occurred late on Monday, but the Tunisian National Guard said reports of a drone attack were “completely unfounded”.

The agency instead suggested that the fire was caused by a cigarette butt or a lighter setting a life jacket ablaze.
