Thank you
A U.S. military official said the raid by special forces targeted the foreign fighter network that travels through Syria into Iraq. The Americans have been unable to shut the network down in the area because Syria was out of the military’s reach.
‘’We are taking matters into our own hands,’’ the official told The Associated Press on condition of anonymity because of the political sensitivity of cross-border raids.
The attack came just days after the commander of U.S. forces in western Iraq said American troops were redoubling efforts to secure the Syrian border, which he called an ‘’uncontrolled’’ gateway for fighters entering Iraq.”
