The Israeli military has boarded Greta Thunberg’s aid boat to stop it reaching the Gaza Strip, her supporters say. Freedom Flotilla Coalition, the group assisting the activists aboard the Madleen sailboat, reported losing contact with the vessel shortly after 1am BST.

The IDF had previously estimated that the flotilla would arrive in Israeli territory an hour earlier. The Madleen's official tracker showed the ship edging closer to the Gaza coas

Israel's Katz said he instructed the military to "take whatever measures necessary" to stop the ship carrying Thunberg and other activists.
