Israeli speedboats are reportedly circling the Freedom flotilla after vowing to intercept the vessel and stop Greta Thunberg reaching Gaza.

Five vessels are said to be surrounding Freedom flotilla, with the captain instructing the team to stay calm and seated with their passports and lifejackets on, according to a UN special reporter with the group.

Francesca Albanese wrote on X: 'I hear them speaking with Israeli soldiers as I type... telling [them] they are carrying humanitarian aid and going in peace. For the time being they are just circled. I am with them, recording everything.'

The group previously claimed they 'will not turn back' as they journey to Gaza despite Israel vowing famous activist Ms Thunberg will never arrive at the war-torn city.

Taking to Instagram, member Yasemin Acar defiantly said the activists would not be returning to Catania, Sicily, from where they set off last Sunday.
