(CNN) -- U.S. forces working with the FBI captured a key suspect in the 2012 attack on the American diplomatic compound in Benghazi, Libya, a U.S. official told CNN Tuesday.

Libyan militia leader Ahmed abu Khattalah was captured over the weekend, the official said. His is the first arrest in connection with the attack.

He is now being held in a location outside Libya, the official said.

Pentagon Press Secretary Rear Admiral John Kirby confirmed Tuesday that the U.S. military and law enforcement personnel captured abu Khatallah on Sunday, and that he is in U.S. custody outside of Libya.

There were no civilian casualties in the operation, and all U.S. personnel involved in the operation have safely departed Libya, Kirby said.

wonder now if we'll hear the Truth what actually occurred that day!

The truth? Everyone already knows the truth....

On the evening of September 11, 2012, Islamic militants attacked the American consulate at Benghazi killing Ambassador Christopher Stevens and Sean Smith, Foreign Service Information Management Officer.

Several hours later, in the early morning of the next day, a second assault targeted a nearby CIA annex in a different compound about one mile away, killing two CIA operatives, Tyrone S. Woods and Glen Doherty.

That's the guy....headed to prison for sure.

We have had eyes on this guy for two years and we magically catch him during an election cycle where Democrats are about to get slaughtered in the House and Senate races. I smell a big hairy vagina here.

If our Coward in Chief took appropriate actions this moron would have been killed a couple years ago when he led the attack against the embassy.

Yup but under the Pinko's Obama and Holder he wont face the Death Penalty. He should NOT be tried in Federal Court and h should be held at G-Bay.

Gitmo should be closed. Just ask John McCain. We try lots of terrorists in our courts. Let's do another one.

We know the truth, Al Qaeda backed militant's launched a coordinated attack against a US Embassy on the anniversary of another major terrorist attack against the US, even though the US knew it was coming and did nothing to prevent it or even to even help the people caught inside as it was happening.

Then we saw Obama's people hit the airwaves saying a Youtube video was behind it.

Obama's Sheeples will believe anything.

Why would I ask Senator McCain? He is about a F'ed in the head as the coward in chief.

Yea and they give the terrorists life in prison when they should be executed or they die of old age before facing true justice for their crimes.
