Security camera footage shows the moment Israeli forces boarded a yacht that was carrying activists towards Gaza, to deliver humanitarian aid.

The 12 activists, including Swedish campaigner Greta Thunberg, were detained and their boat, the Madleen, was towed to the Israeli port city of Ashdod.

The Madleen's journey was organised by the Freedom Flotilla Coalition, a campaign group that has been trying to breach a blockade on Gaza that was imposed by Israel in 2007 when Hamas took control of the territory.

The activists who set sail on 1 June, said the goal of the mission, which carried a small amount of supplies including rice and baby formula, was to raise awareness of the current humanitarian crisis in Gaza caused by Israel's restrictions on the delivery of aid.

Israel dismissed it as a"selfie yacht", saying it would deport the activists to their home countries.
