Transcript for America's Biggest Enemy Growing in Strength in Iraq
And next, big news, tonight, from overseas. There is a worrying, new sign that al qaeda is on the march in two countries cracked by war. One of them iraq, where so many brave american troops fought to create a future. Here's terry moran on the extremists rising. Reporter: Fierce fighting raged on the outskirts of fallujah today. Iraqi troops blasting their way down the streets. After a decade of u.S.-Led war to plant democracy in iraq, much of fallujah has now fallen to al qaeda. The terror group's infamous black flag flies openly there now. And its masked soldiers are everywhere, rpg launchers in hand.

More than 100 marines gave their lives to pacify the city and hundreds more were injured. Today, with american troops out of iraq, security has collapsed. And the civil war in next door syria, where al qaeda fighters are growing in strength and taking the lead among rebel forces, is now spilling over freely into iraq. The fear now is that al qaeda might actually form its own state, its own power base, within the chaos. Secretary of state kerry said this weekend the u.S. Stands ready to help iraq in this battle, to a point. We're not contemplating putting boots on the ground. This is their fight. Reporter: And right now, they're losing. Terry moran, abc news, london.
