Two Tunisians have been arrested in Turkey in connection with the September killing of US Ambassador Chris Stevens in Libya, Turkish media reported Thursday evening. The Hurriyet later published the story in English.

Stevens and three other Americans were killed when terrorists attacked the US consulate in Benghazi on September 11.

Officials originally said the attacks were tied to anti-US protests over an anti-Islam film, but later said the consulate was the target of a planned terror offensive.

According to the new reports, the two suspects were arrested Wednesday night at Istanbul’s Ataturk airport and were carrying forged passports.

The suspects were now said to be in custody in Turkey.
