CATALAN — A ship carrying activists 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.

The Freedom Flotilla Coalition protested the return of the other migrants to Libya, where human rights campaigners have said they face abuse and even torture.

It also has called on Italy, Greece and Malta to pick up those now on board the Madleen and bring them to safety in Europe.

Swedish climate campaigner Greta Thunberg is among the 12 activists aboard the Madleen which departed Sicily on Sunday on a mission that aims to break the sea blockade on Gaza and deliver humanitarian aid while raising awareness over the growing humanitarian crisis in the Palestinian enclave.

The voyage is expected to last seven days.

Among the others on board are “Game of Thrones” actor Liam Cunningham and Rima Hassan, a French member of the European Parliament who is of Palestinian descent.

She has been barred from entering Israel due to her active opposition to the Israeli military operation in Gaza.

After an almost three-month blockade aimed at putting pressure on Hamas, Israel started allowing some basic aid into Gaza last month, but humanitarian workers have warned of famine unless the full flow of supplies resumes.

Almost all of Gaza’s population of 2.3 million is acutely malnourished and one in five Palestinians are on the brink of starvation, the World Food Programme has warned.

An attempt last month by the Freedom Flotilla to reach Gaza by sea failed after another of the group’s vessels was attacked by two drones while sailing in international waters off Malta.

The group blamed Israel for the attack which damaged the front of the ship. — Euronews
