Two suspects in the killing of US ambassador to Libya Christopher Stevens have been detained at İstanbul's Atatürk International Airport, Turkish broadcaster Kanal D reported on its website on Friday.
It said Turkish police held the two suspects, described as Tunisian citizens, as they tried to enter the country with fake passports, Todays Zaman reported.
Police in İstanbul declined comment on the report.
Stevens was one of four Americans who died when Islamist gunmen stormed the Benghazi consulate last month.
