A NATO soldier was killed Thursday in an insurgent attack in the restive southern Afghanistan. "An International Security Assistance Force (ISAF) service member died following an insurgent attack in southern Afghanistan today," the NATO-led ISAF confirmed in a statement. The brief statement did not disclose the nationality of the victim under the ISAF policy. Troops mainly from U.S., Britain and Australia have been stationed in the southern region within the framework of ISAF to curb Taliban-linked insurgency there. A total of 340 foreign soldiers have been killed in Afghanistan so far this year.
