The lawyers for two Greek soldiers arrested in Turkey have formally requested their release from custody.
The two were arrested last week for allegedly entering a Turkish military zone and on suspicion of attempted espionage.
Greece said the two soldiers — a lieutenant and a sergeant — accidentally strayed into Turkey during a patrol of the Greek-Turkish border, due to bad weather.
The development has added to strained ties between the NATO allies.
Lawyers filed a demand for their release with the court in the northwestern Turkish city of Edirne on Monday.
The private Dogan news agency said court officials had begun considering the case.
A river marks most of the border, while a fence runs along much of the land section. However, some parts aren't clearly marked.
