Israel has issued an ominous warning to Greta Thunberg, claiming the environmental activist will not make it to the Gaza Strip on her 'freedom flotilla'.

Ms Thunberg, 22, is among 12 activists on board the ship, hoping to 'break [Israel's] siege on the Gaza Strip' with a delivery of humanitarian aid.

She is joined by Game of Thrones actor Liam Cunningham and Rima Hassan, a French MEP, aiming to raise awareness of the ongoing crisis in the region.

The vessel is expected to reach Gaza this weekend, having set off from Catania in Sicily last Sunday.

But the Israel Defence Forces has now been ordered to stop the ship in its tracks and has accused Ms Thunberg of being an 'antisemite travelling with Hamas propogandists'.
