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.

A vessel that was approaching Freedom Flotilla Coalition's Gaza-bound charity ship the Madleen has left, the coalition said early on Monday, after an alarm was sounded on the ship warning of a possible interception.

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.
