More than 300 migrants have been rescued by the Greek Coastguard from a stranded fishing boat and transferred onto an oil tanker.
The operation took place in roughish seas near Crete. The migrants including 40 children and 24 women will later be taken to a holding centre on the island.
Greece is a major transit point for illegal entry of migrants hoping to get to the European Union.
Ministry officials said the migrants were in good health but refused to confirm if most of those on board were from Syria and Egypt.
