A terrorist who allegedly recruited Afghan children to serve as suicide bombers has been taken into custody, US officials said on Sunday.
The arrest was made south of the Afghan capital of Kabul. A second rebel sympathiser was taken into custody Saturday in Logar province.
The two belonged to the Hakkani Network, considered to be "one of the deadliest Taliban organisations" and had been active in the troubled Afghan area along the Pakistani border.
US-led coalition troops and Afghan soldiers participated in the mission.
On Saturday, two soldiers of the NATO-led International Security Assistance Force (ISAF) were killed by militants in southern Afghanistan, military officials reported. The soldiers' nationalities were not known.
US and Afghan troops began a major anti-Taliban offensive in Afghanistan's southern province of Helmand on Thursday, with support from British troops.
