Swedish climate activist Greta Thunberg is set to join the sailing of a humanitarian aid ship to Gaza this weekend. The group, which also consists of several other high-profile activists, will board the Freedom Flotilla Coalition (FCC) ship "Madleen" from Catania in Sicily on Sunday to deliver vital supplies "to break Israel's illegal siege, to stop their starvation of Palestinians... [and] their genocide in Gaza," according to the ativist group.
