This photo provided by the Hellenic Coast Guard and taken from a vessel shows a ship with migrants near the southern island of Crete, Greece , Oct. 29, 2021.
The ship had sent a distress signal on Friday after its engines failed in international waters, according to Greek authorities who allowed it to dock at the southeastern Aegean island of Kos early on Sunday.
The Greek Coastguard said the migrants were transported to a reception center on the island while news reports said health ministry experts would quarantine them and test them for the coronavirus.
The migration ministry said nearly 400 people disembarked from the ship, with six of them detained for questioning, but did not immediately list their nationalities.

Both Greece and Turkey have accused the other of failing to honour the agreement sealed after more than a million migrants and asylum seekers, many from the civil war in Syria, entered the EU in 2015.
Plakiotakis said Turkey "won't accept the return of the Turkish-flagged ship that sailed off a Turkish port."
He added that the ship set sail "obviously with the knowledge of the Turkish coastguard and (Turkey) continues to have no regard for human lives."

On Tuesday, four migrants, two of them children, drowned after a boat sank off the island of Chios.
The vessel had set out from Turkey amid strong winds, and none of the occupants had been given a life vest by the smugglers, the Greek Coastguard said in a statem
