An explosion which killed an American and an Afghan soldier on an army base in Kabul this week was carried out by a suicide bomber, the U.S. military has confirmed, the second time in five months an insurgent has managed to infiltrate a base. On Monday, NATO said one of its service members had died and several had been wounded in an explosion on an Afghan army base in the capital but gave no details. One Afghan soldier was also killed in the blast and three were wounded, Reuters reported. Taliban spokesman Zabiullah Mujahid said the attack was carried out by a Taliban infiltrator, who struck while foreign advisors were training Afghan troops. The U.S. Defense Department has now confirmed it was a suicide attack. "Sergeant Robert J. Barrett, 20, of Fall River, Massachusetts, died April 19 in Kabul, Afghanistan, of injuries sustained when a suicide bomber attacked his unit," the department said in a statement.
