A County Tyrone man, detained by Greek authorities after a dispute aboard an aid ship, has been freed.
David Callander was one of 55 activists taking supplies to Gaza via Egypt on a chartered ship last week.
It is claimed the vessel unexpectedly set sail from Libya for Greece with 12 aid workers on board.
Mr Callander and former US Marine Ken O'Keef, an Irish national, faced minor charges of disturbance and damage before being set free.
The Ireland-Palestine Solidarity Campaign (IPSC) said the Strofades IV had been chartered to take the aid activists from Derna in Libya to an Egyptian port from where the aid was to be taken overland to Gaza.
