Three boats belonging to the international aid initiative, Global Sumud Flotilla (GSF) set sail from Tunisia’s Bizerte port on Saturday (September 13) to deliver vital supplies to Gaza and break Israel's naval blockade.

Activists aboard a vessel called Marinette waved as they sailed off. Another set of activists carried the flag of Algeria and the flag of Poland as they departed.

Organisers said more boats are expected to depart from Tunisia, with the delay attributed to poor weather and logistical challenges.

GSF said on Wednesday (September 10) that one of its boats was attacked by a drone at a Tunisian port, the second such strike in two days. Organisers described the attacks as deliberate attempts by Israel to disrupt the mission.

The Israeli military did not respond to a request for comment.

The GSF is a “a coordinated, nonviolent fleet of mostly small vessels sailing from ports across the Mediterranean to break the Israeli occupation's illegal siege on Gaza,” according to its website and includes hundreds of activists from over 40 countries including Swedish activist Greta Thunberg and Portuguese left-wing politician Mariana Mortagua.
