Aegean zones complicate Nato migrant rescues

He said Nato’s task “is not to turn back the boats” but to spot boats and alert the Greek and Turkish coastguards and EU border control agency Frontex.

With dozens of dinghies crossing each day, he noted that Nato vessels are, under international law, obliged to rescue people at risk of drowning.

“In case of rescue of persons coming via Turkey, they will be taken back to Turkey,” he said.

The statement means that anybody rescued by Nato, which has up to five ships in the area, would go back to Turkey because all the migrants are coming from Turkey to Greece.

“[Rescued] people coming from Turkey will be handed to Turkish authorities,” a Nato official told EUobserver.

Turkish reading

Meanwhile, Turkey has its own reading of the accords.

In terms of surveillance, Turkey says that if Nato spots a migrant boat in Turkish or international waters, it has to inform the Turkish coastguard, which will return them to Turkey.

But if Nato spots a boat in Greek waters, it tells the Greek coastguard, which has to take care of the people on board.

In terms of rescues, a senior Turkish official told EUobserver: “If Nato rescues people in Greek waters, it still has to notify Greeks, not to give them to Turkey.”

The small print is significant because of the mosaic of Greek and Turkish maritime zones, a source of dispute in the past.

Flag states

Meanwhile, Nato itself has no responsibility for rescues.

The Nato official told EUobserver: “Nato doesn’t have a juridical personality. It’s an intergovernmental, multinational organisation.”

Nato member countries rotate vessels in and out of the Aegean “maritime group”.

If one of them finds a migrant boat in distress, its own flag state, not Nato as an institution, is responsible for keeping them from harm.

“If allied vessels encounter people in distress at sea, they have to live up to their national responsibility to assist,” Stoltenberg said on Thursday.
