Deputy interior minister Gen. Ayub Salangi said the two suicide bombers were arrested in Gresh district.
Gen Salangi also added that four anti-government armed militants were blown up by their own explosives in northern Faryab province.
He said the incident took place in Shirin Tagab district while the militants were placing improvised explosive device (IED) on roadside.
According to Gen. Salangi, at least militants were also injured following the explosion.
The anti-government armed militant groups including the Taliban militants frequently use improvised explosive device as the weapon of their choice to target Afghan and coalition security forces, however the ordinary civilians are mostly targeted in roadside bombings.
