Eight men believed to be part of a military coup in Turkey have requested political asylum in Greece, the Greek police ministry has said.
A Turkish military helicopter landed in Alexandroupolis in northern Greece after government forces took back control of Istanbul, and the eight on board were arrested.
Factions of the Turkish military attempted to overthrow the government, using tanks and attack helicopters, but citizens loyal to President Tayyip Erdogan helped to foil the plan.
Greek state television ERT said the men arrested may have been involved in the uprising.
On Twitter, Turkish foreign minister Mevlüt Çavuşoğlu said the government had asked Greece to return the "treacherous soldiers" immediately.

Nearly 1,700 military personnel have been sacked and 130 media outlets shut down as the crackdown continues following the failed coup.
The dispatch comes after President Erdogan called on US to hand over cleric Fethullah Gulen, who he blames for Turkey's failed coup.
Turkey has been warned of the consequences of imposing the death penalty as punishment to those involved in the failed coup attempt.
