KABUL (AFP) - A series of makeshift bomb attacks killed a NATO soldier and three Afghan policemen in eastern and southern flashpoints of the war-torn country, authorities said Thursday. An International Security Assistance Force (ISAF) service member was killed by an improvised explosive device in eastern Afghanistan yesterday, the alliance said in a statement without giving further details. Two Afghan policemen were killed and four people, including two women passers-by, wounded when a roadside bomb ripped through a police vehicle in the southern province of Kandahar on Wednesday, the interior ministry said. A third policeman was killed and one wounded in a similar attack in neighbouring Helmand province on Thursday, a statement by the ministry said. It also said three terrorists were killed while the bomb they were planting on a road in the Nad Ali district of Helmand went off prematurely.
