The Canadian ship "Tahrir", participating in the flotilla to Gaza, attempted to depart Monday from the Greek port of Agios Nikolaos, but was intercepted by the Greek coast guard shortly after departure.
The Greek coast guard boarded the Canadian ship after the Greek authorities had banned the departure of all ships to Gaza from its ports.
As the Canadian ship departed from the port with all passengers on board wearing life vests, the Greek coastguard tracked the ship in the water and boarded it within minutes.
After seizing the ship, coast guard officers asked who was the captain but the passengers refused to reply, with every passenger saying that he was the captain.
Some of the passengers yelled "release our ship!" and one of the protesters asked two coast guard officers whether they had children, and whether they were thinking about the children in Gaza.
Greek coast guard officers are currently sailing the Tahrir back to the port, and the passengers are all due to be taken into custody by Greek authorities.
On Sunday, the organizers of the Gaza flotilla announced that the flotilla ships anchored in Greek ports are planning to set sail to Gaza on Monday. The decision came despite the Greek's governments ban on any ships to depart from its ports to Gaza.
On Monday, as a compromise, the Greek government offered to send the flotilla's humanitarian aid to Gaza with Greek diplomats, under United Nations supervision. Israel has agreed to the offer.
