According to local authorities in southern Helmand province of Afghanistan, at least two Afghan national army service members were killed following a roadside improvised explosive device blast in Garmser district on Monday.

Garamser district chief Ayoub Omer confirming the report said the incident took place early Monday after the vehicle of the Afghan national army soldiers struck with a roadside bomb.

In the meantime a spokesman for the Taliban group Qari Yousuf Ahmadi claimed responsibility behind the incident and said 4 Afghan national army service members were killed in the blast however local officials denied the claims.

Taliban militants frequently use improvised explosive device as the weapon of their choice to target Afghan and coalition security forces but in a number of cases Afghan civilians become the victims.

An average number of 243 Afghan national army soldiers are killed or injured in militants attacks in Afghanistan in 2012, according to ISAF.
