Israel has threatened to block Greta Thunberg's 'freedom flotilla' from delivering aid to Gaza.
The climate activist and 11 pro-Palestine campaigners set sail on Sunday on a ship aimed at 'breaking Israel's siege' of the territory.
The boat Madleen, operated by activist group Freedom Flotilla Coalition, departed from Catania, Italy, and is carrying a 'symbolic' amount of aid.
Videos posted to TikTok show the young activists smiling, swimming and filming social media content as the vessel makes its journey across the Mediterranean.
But the Israeli Army says it is 'prepared' to raid the ship, as it has done with previous freedom flotilla efforts.
