A flotilla of boats headed for Gaza carrying 350 pro-Palestinian activists - including climate change campaigner Greta Thunberg - has departed from Barcelona.
Around 20 vessels displaying Palestinian flags left the Spanish port at 19:00 local time on Monday, stocked with medical and food supplies.
The flotilla first attempted to set sail on Sunday, but had to return to port due to stormy weather.
The aim of the mission is to "break Israel's illegal siege on Gaza", the organisers said - though a previous attempt to reach Gaza by sea was intercepted by Israeli forces.
The Global Sumud Flotilla Mission plans to launch in two waves - the first from Barcelona and the second from Tunis on 4 September.
