If you are an American citizen named Amiir Farouk Ibrahim and you're fighting with al-Qaeda linked rebels in northern Syria, your passport has been found.

Among documents recovered in northern Syria by the Syrian Observatory for Human Rights was a passport issued by the United States, belonging to the 32-year-old, who has dual citizenship between the United States and Egypt.

He was born in Pennsylvania, and his passport was issued in 2012.

He is not the first American to be linked with the Syrian rebellion. Back in May, a Michigan woman was killed while fighting alongside rebel forces.

And in March, we reported on a U.S. Army veteran in trouble with the F.B.I. for taking up arms with known terrorist organizations in fighting the Syrian regime.

All told fighters from more than 25 countries have enetered the conflict.

The Syrian Observatory for Human Rights found identifying paperwork from Qatar, Bahrain, United Arab Emirates, Iraq, Turkey, Tunisia, Saudi Arabia, and Egypt.
