Afghanistan's insurgent group Taliban has claimed the responsibility for the explosion that took place near Bagram airfield, saying it was a retaliation for the United States distributing propaganda material that insulted Islam.
Local officials said that at least six people got injured after a suicide bomber on a motorcycle detonated his explosives outside an entry checkpoint to the base, The Guardian reported.

Meanwhile, a U.S. military official General James Linder, in a statement, said, "The design of the leaflets mistakenly contained an image highly offensive to both Muslims and the religion of Islam."
