BAGHDAD, Feb 6 (Reuters) – Al Qaeda videos seized by U.S. forces show Iraqi children younger than 11 carrying out mock kidnappings and attacks, the U.S. military and Iraqi officials said on Wednesday. Videos played to media showed about 20 boys, mostly under 11, wearing balaclavas and brandishing AK-47 assault rifles and rocket-propelled grenade launchers almost as big as themselves. MORE
