Borno - Boko Haram's leader, Abubakar Shekau, has claimed responsibility for attacks on military formations in Borno State.
Few believe the Boko Haram terrorist network has such capability despite fears its insurgency could reach neighboring states.
In the video received Thursday, Abubakar Shekau dismisses last month's U.S. designation of his group as a terrorist organization and suggests a country that could not stop the 9/11 attacks cannot hurt his movement.
Thousands have been killed in the Nigerian insurgency since 2009.
The video shows burning buildings and aircraft in the December 2 attack on an air force base outside Maiduguri and warns, "Don't think we will stop in Maiduguri. Tomorrow you will see us in America itself."
