Before making the decision to reroute, Mano Maritime said in a statement: "[We are] in contact with the local authorities and as a result of the protests, there is a slight delay in disembarking passengers.
“The time spent in the port will be extended accordingly and the excursions there will not be affected.
"There are no armed police on the ship, only Israeli security personnel as is customary. The estimate is that the demonstration will disperse within half an hour.
