Scores of Syrian refugees who recently arrived on the Greek island of Kos began registering early Sunday on a ship sent by the government following tensions over a huge influx of arrivals.

The Eleftherios Venizelos, docked in Kos since Friday, will be moored for about two weeks, officials say. Officials on board will register Syrians who are already on the island as well as any newcomers, regardless of nationality, according to UN refugee agency spokeswoman Stella Nanou.

A group of migrants who had just been rescued at sea were brought to the entrance of the ferry, an AFP journalist said, though it was unclear whether they could be received immediately.
