A Taliban improvised explosive device attack coordinator was captured in operation carried out by the Afghan forces and the NATO-led coalition troops in the country's northern province of Kunduz, the coalition forces said on Sunday.

"An Afghan and coalition security force arrested a Taliban improvised explosive device (IED) attack coordinator in Khanabad district, Kunduz province, Friday," the International Security Assistance Force (ISAF) said in a press release.

The captured man planned and executed IED attacks throughout Khanabad in the province 250 km north of Kabul, it said.

"He is believed to have conducted attacks against Government of the Islamic Republic of Afghanistan officials as well as Afghan and coalition forces," the release noted, adding that the security force also seized IED-making materials during the raid.

The IEDs used in making suicide vests and roadside bombs has proved a challenge for Afghan and some 100,000 NATO-led forces in the insurgency-hit country, as they are simple but difficult to be detected.

Taliban militants often attack security forces with IEDs and roadside bombs but the lethal weapons also inflict casualties on civilians.

On Saturday, four members of a family and a driver were killed when a vehicle touched off a roadside planted bomb in southern Helmand province.
