WASHINGTON (CBSDC/AP) — Turkish media is reporting that two Tunisians are in custody in connection to the terrorist attack on the U.S. Consulate in Libya that killed Ambassador Christopher Stevens and three other Americans.

According to the Hurriyet report picked up by The Times of Israel, the two suspects were arrested at Istanbul’s Ataturk Airport Wednesday night for allegedly carrying forged passports.

This report comes as FBI officials examined on Wednesday the Benghazi complex that was attacked on Sept. 11.

FBI spokeswoman Kathy Wright told The Associated Press that the investigators were only there for one day.

An official told CBS News only potential evidence was gathered from the scene.

Questioned at a press conference Thursday why it took investigators nearly four weeks to get to Benghazi, Attorney General Eric Holder said people should not assume that “all that we could do or have been doing” in the investigation is restricted solely to Benghazi.

Holder added: “I’m satisfied with the progress.”

Republicans, though, have not been satisfied and say the White House should’ve been prepared for this type of attack and accuse the Obama administration of putting out misinformation about the attack.

Secretary of State Hillary Clinton said the State Department is committed to the investigation.

“No one wants the answers more than we do here at the (State) Department,” Clinton told CBS News.
