Hundreds of Syrian migrants on the Greek island of Kos on Sunday began boarding a passenger ship that is to house and process them, in a bid to ease sometimes chaotic conditions onshore. Greek officials had delayed the embarkation at the quayside in Kos for more than a day, working on plans to avoid disorder among the increasingly desperate migrants who have arrived on the island in dinghies and small boats from nearby Turkey. The boarding of the car ferry Eleftherios Venizelos, which arrived in Kos on Friday, began in the cooler night hours in an organised and orderly fashion.
