MILAN (AP) — A ship carrying activists, including Greta Thunberg, to Gaza to deliver humanitarian aid rescued four migrants on Thursday after they had jumped into the sea from another vessel to avoid being picked up by Libyan authorities.

The vessel Madleen, which is operated by the Freedom Flotilla Coalition, was alerted by the European Union’s Frontex border control agency and arrived at the location in the Mediterranean where it found 30-40 people on a “boat that was rapidly deflating.” As the Madleen launched its own inflatable rescue boat, a Libyan coast guard vessel approached at high speed, the coalition said.

“To avoid being taken by the Libyan authorities, four people jumped into the sea, and began desperately swimming toward the Madleen,’' which rescued them.
