Huge crowds gathered at Tunisia's port on Sunday to welcome Greta Thunberg as her aid flotilla, bound for Gaza, docked at the port.

The Swedish climate activist is travelling with 350 pro-Palestinian activists on boats stocked with aid that they are hoping to deliver to Palestinians in Gaza.

Pictures from the Sidi Bou Said port show hordes of people surrounding the 22-year-old as she addressed the crowd. We all know why we are here, she said. Just across the water there's a genocide going on, a mass starvation by Israel's murder machine.

Israel has repeatedly denied that there is starvation in Gaza and has blamed any hunger on Hamas and aid agency failures.

Last month a UN-backed body confirmed that there was famine in the territory and the UN's humanitarian chief said it was the direct result of Israel's systematic obstruction of aid entering Gaza.

French-Palestinian Member of the European Parliament Rima Hassan was at the port, stating, The Palestinian cause is not in the hands of governments today. It is in the hearts of peoples everywhere, showing solidarity with the Palestinian people.

Flotilla organizers have said that the aim of their mission is to break Israel's illegal siege on Gaza, though previous attempts have been met with resistance. The current flotilla set sail from Barcelona and aims to expand its efforts in Tunisia before completing its journey to Gaza.
