Six foreign migrants suffering from hypothermia were being treated at a hospital in Hania on Saturday, with one of them, a young girl, deemed to be in critical condition.

The six patients were rescued after their boat went down 300 miles east of Malta and were flown to Greece, which was the nearest landfall in helicopter range.

According to reports, more than 20 migrants were missing from the same wreck.

“The survivors, including a girl in critical condition, are suffering from hypothermia and were hospitalized in Hania,” a spokesman for the Greek port police told AFP on Saturday.

The six survivors were rescued by two cargo ships, one British and one Libyan, who spotted them in the water.
