The second attack shots demanded on Greta Thunberg Gaza Flotilla

Activists say a ship, which is part of the aid that carries a load in Gaza, was hit in a suspected drone. It is the second suspected attack in two days.

The Swedish activist Grita Thunberg is among the activists traveling to Gaza with the fleet to try to break the naval blockade of Israel.

BBC checks the analysis of the accidents and spoke to two arms experts who say that the device on the plane after the attack appears to be a hand grenade. Merlin Thomas reports.
