Suicide bomber kills 2 at Bagram air base

(CBS/AP) A suicide bomb attack at the NATO base where copies of the Koran were burned last month killed at least two civilians and injured five more, Afghan officials said Monday.

A suicide bomber, who was also killed in the explosion, targeted the gates at Bagram air base, north of Kabul. The Taliban claimed responsibility for the attack and said it was retribution for the Koran-burning, according to a text message to the media from spokesman Zabihullah Mujahid.

Capt. Justin Brockhoff, a NATO spokessman, said there were no reports of NATO fatalities, and the base was not breached by the explosion.

"Coalition officials are gathering details at this time, and more information may be released as appropriate," he said.

The U.S. has said the burning of the Muslim holy books last month was unintentional, but the incident sparked a rash of deadly protests and attacks on U.S. forces - more than 30 Afghans were killed in the protests and six U.S. soldiers have been killed by rogue Afghan forces in the aftermath of the Koran burnings.
