The Israeli Ministry of Foreign Affairs says the Madleen’s crew is being taken to Israel after Israeli commandos seized the vessel in international waters. The Madleen ship, launched by the Freedom Flotilla Coalition, was close to 100 miles [160km] from Gaza when it was stopped. The ship was carrying humanitarian aid to Palestinians starving because of Israel’s siege. Israel’s most recent total blockade began on March 2, and has only partially lifted under mounting international pressure.
Israel is an invading country currently performing the biggest live-streamed genocide in recent history. They don't care about international law or what people in the rest of the world think. So their boarding or attack of the freedom flotilla does not care about reasonable use of force.
It's not the first time the flotilla is intercepted by Israeli forces. A few months ago a ship from freedom flotilla was sunk by Israeli drones, with some of the activists that are currently on board in the Madleen (such as Thiago Ávila). But it's the first time a high profile activist like Greta Thunberg is joining their initiative.
