The Freedom Flotilla Coalition (FFC) has said the Israeli military has boarded its Gaza-bound aid ship carrying Greta Thunberg and that communication with the boat has been lost.

The activists had set out to protest Israel’s ongoing military campaign in the Gaza Strip, which is among the deadliest and most destructive since World War II, and its restrictions on the entry of aid.

The British-flagged yacht Madleen, which is operated by the pro-Palestinian Freedom Flotilla Coalition, was aiming to deliver symbolic aid to Gaza.
