Activists on Greta Thunberg's Gaza flotilla who alleged it was targeted by a 'drone attack' off Tunisia overnight said Tuesday they remained 'determined' to reach the war-ravaged territory.

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

A boat carrying Greta Thunberg towards Gaza has reportedly been set ablaze in a suspected drone strike off the coast of North Africa.
