Operated by the pro-Palestinian Freedom Flotilla Coalition (FFC), the British-flagged Madleen yacht set sail from Sicily on June 6 and is currently off the Egyptian coast, heading slowly towards the Gaza Strip, which is besieged by Israel.

Israel’s government has vowed to prevent an aid boat carrying Greta Thunberg and other activists from reaching the Gaza Strip.

Israel won’t allow a flotilla of activists — including Swedish environmentalist Greta Thunberg — sailing toward the Gaza Strip to reach the coastal enclave, Defense Minister Israel Katz said on Sunday.
