Fort Leavenworth ? An Army colonel from Fort Leavenworth is among those killed in an insurgent attack in Afghanistan.

Army officials said Thursday that 46-year-old Col. John McHugh, of Newark, N.J., died Tuesday after his convoy was stuck by a suicide car bombing. The attack, the deadliest on NATO forces in Kabul in eight months, killed four other U.S. soldiers and a Canadian.

McHugh was serving as chief of Operations Group A with the Battle Command Training Program based at Fort Leavenworth. He was on a training mission at the time of the attack.

He graduated from the U.S. Military Academy in 1986 and also had degrees from American Public University and U.S. Army War College.

He is survived by his wife, five children and one granddaughter.
