The anti-government armed militant groups frequently use explosives materials for the roadside bombings and car bombings to target the government staff and security personnel.
However, in majority of such incidents the ordinary civilians are targeted besides such bombings incur casualties to the security personnel and in some cases the Taliban militants themselves are killed or wounded.
At least two Taliban insurgents were killed while planting Improvised Explosive Devices (IEDs) in eastern Laghman province of Afghanistan nearly three weeks ago.
