The International Committee to Break the Siege on Gaza said the “Global Sumud Flotilla” will begin its journey from Barcelona on Sunday, followed by a second departure on Thursday from Tunisia, to challenge Israel’s siege of the coastal enclave.

In a statement, the committee described the flotilla as a worldwide protest against “the siege and genocide” in Gaza, accusing international institutions of “failure and complicity”.

It stressed the convoy is “not just symbolic boats carrying aid, but a powerful humanitarian message” reflecting global determination to end the siege.

“Every ship carries a cry of hope for Gaza and a global voice demanding an immediate end to the blockade and injustice,” the statement said.
