The FBI is expected to question a suspect in the deadly attack on the U.S. consulate in Benghazi, Libya, "in the coming days," according to a U.S. government official with direct knowledge of the investigation, CNN reported.
The suspect, Ali Ani al Harzi, first caught the attention of the United States after he posted details of the attack as it was happening on social media websites.
At the request of the United States, Turkish officials detained al Harzi when he entered that country after leaving Libya. Turkey then transferred him to Tunisia, where he is being held.
"We are very pleased the Tunisian government is working with American investigators to allow in person access to Ali Ani al Harzi. Under this arrangement the interviews will be under Tunisian supervision and consistent with their sovereignty and meets the needs of our investigative team," U.S. Senators Lindsey Graham and Saxby Chambliss said in a statement Saturday.
"Allowing American investigators in person access will make the interview more meaningful and is a welcome breakthrough in our efforts to find the perpetrators of the Benghazi Consulate attacks," they added.
The deadly September 11 attack on the U.S. Consulate in Libya resulted in the death of Ambassador Christopher Stevens and three other Americans.
"We're continuing to look at any and all leads," the official said, declining to say how many others suspects are under investigation.
