Turkish security officials tell Al Jazeera the two men are restaurant workers without ties to the government.
Turkish officials have denied reports that two Turkish nationals who were captured by forces loyal to renegade military commander Khalifa Haftar in Libya are spies.
Restaurant workers Mehmet Demir and Volkan Altinok were arrested by Haftar’s eastern-based forces in Tripoli’s southern Qasr bin Ghashir district on April 12.
They have since been sent to Grenada prison in al-Bayda, a city located about 200km east of Benghazi.
The men were arrested just days after Haftar launched an offensive to seize control of Tripoli, which houses the UN-recognised Government of National Accord (GNA).
