Global Sumud Flotilla has departed from Barcelona carrying 350 international activists and humanitarian aid bound for the Gaza Strip. The mission is the largest civilian maritime attempt in years to challenge Israel’s naval blockade. Around 20 boats left the port on Monday evening after strong winds forced a delay on Sunday. Organisers confirmed the convoy is carrying food and medical supplies, with more vessels expected to join from Tunisia and Sicily. The departure took place at 19:00 local time following a general assembly of volunteers. Safety concerns had earlier pushed the flotilla back to port when winds surpassed 30 knots, posing risks to smaller vessels.

The flotilla will take seven to eight days to complete its route and will regroup in Tunis before heading east across the Mediterranean toward Gaza. Activists from 44 countries are taking part, including Greta Thunberg, Thiago Avila, Ada Colau Ballano, Liam Cunningham, and Eduard Fernandez. All participants emphasise that they are travelling as civilians without government or political ties. Thunberg released a video statement before departure saying, “We are sailing again to break the siege and open up a humanitarian corridor.”
The mission is coordinated by four activist coalitions: the Global Movement to Gaza, Freedom Flotilla Coalition, Maghreb Sumud Flotilla, and Sumud Nusantara. These groups have organised previous attempts to break the blockade, but most missions have been intercepted by Israeli naval forces, often in international waters. This is the third sea mission in recent months aimed at delivering aid directly to Gaza. Earlier efforts were intercepted and participants detained. In June, Thunberg and others were removed from the yacht Madleen by Israeli forces about 185 kilometers from Gaza and deported after being taken to Ashdod port.
Israeli officials have dismissed the flotillas as symbolic, describing them as publicity stunts that provide limited relief. The government continues to enforce strict controls on aid deliveries. Although a partial easing of restrictions took place in late May, international agencies report that famine conditions persist in parts of Gaza. The convoy carries food and medical supplies, though organisers admit the quantity is limited by vessel size. Their purpose is not only to deliver aid but also to highlight the humanitarian crisis and question the legality of the blockade. The steering committee includes activists such as Saif Abukeshek, Yasemin Acar, Kleoniki Alexopoulou, Marouan Ben Guettaia, Torkia Chaibi, Maria Elena Delia, Hayfa Mansouri, Karen Moynihan, Muhammad Nadir al-Nuri, Wael Nawar, Melanie Schweizer, Thiago Avila, and Greta Thunberg.
Organisers describe the Global Sumud Flotilla as the most significant maritime effort since 2010, when Israeli forces boarded the Mavi Marmara. That incident resulted in the deaths of 10 activists and drew global condemnation. The Mavi Marmara had been carrying more than 600 passengers and aid supplies. Between 2008 and 2016, 31 boats attempted to reach Gaza. Only five managed to dock, and none since 2010 have entered Gaza waters without interception.
The humanitarian situation in Gaza remains severe. According to the Gaza Ministry of Health, more than 63,000 people have been killed and over 160,000 injured since the Israeli offensive began in October 2023. Many civilians have been displaced as bombardment continues, particularly in Gaza City. Israel introduced a system to manage aid through the Gaza Humanitarian Foundation, bypassing international groups. Aid organisations have questioned its transparency and effectiveness. At the Barcelona send-off, punk musician Bob Vylan expressed support, calling the volunteers “brave individuals” who act where governments have failed.
The flotilla expects to reach Gaza by mid-September. Organisers have kept navigation details undisclosed due to security risks, noting that previous flotillas were intercepted before approaching the Israeli-declared naval exclusion zone.
