The Justice Department has filed criminal charges against several suspects in the Benghazi terror attack, a U.S. official tells Fox News.

The U.S. official confirmed that sealed charges were filed against suspects in connection with the Sept. 11, 2012, attack. It’s unclear whether they are the same individuals whose images the FBI released to the public in May.

One of the individuals charged is Libyan militia leader Ahmed Khattalah.

Four Americans, including then-Ambassador Chris Stevens, were killed in the attack on the U.S. compound in Benghazi.

The administration was staying mum on the charges. Asked about the reports, a Justice Department official said only that their investigation is “ongoing.”
