The incident took place in Asmar district after an Improvised Explosive Device (IED) went off, leaving the group’s district shadow judge dead.
The security sources further added that two other Taliban militants were killed while they were planting an Improvised Explosive Device (IED) in Greshk district of southern Helmand province.
The incident took place after the explosives went off prematurely, leaving both the militants dead.
The anti-government armed militant groups including the Taliban insurgents have not commented regarding the report so far.
This comes as at least 5 Taliban insurgents were killed in a similar incident in southeastern Paktia province of Afghanistan late last month.
The Taliban insurgents and militants belonging to the other insurgent groups are frequently using Improvised Explosive Device (IED) as the weapon of their choice to target the security forces.
The IEDs are the main contributors to the casualties of the Afghan security forces but are also considered as a key factor in growing civilian casualties.
Earlier, a commander of the Taliban group Hafiz Saadullah was among ten militants killed after blown up by own explosives in southeastern Ghazni and western Herat provinces last month.
An Improvised Explosive Device (IED) expert of the Taliban group was also killed in an explosion in northern Kunduz province of Afghanistan last month.
