The activists were detained when Israeli forces intercepted boats trying to breach its naval blockade of Gaza to deliver aid.

The Swedish activist tells the BBC that no one would "risk their life" purely to gain attention.

BBC Verify analyses footage of the suspected drone attacks and images of a device found after the incident.

Organisers said two boats were hit in separate incidents; Tunisian authorities disputed the first and have not commented yet on the second.

The boats, carrying 350 pro-Palestinian activists and stocked with medical and food supplies, are en route to Gaza.

Around 20 boats have left the port of Barcelona with Greta Thunberg and aid supplies on board.

Onboard security footage from the Madleen aid vessel shows activists throwing their tech overboard and putting up their hands.
