Brussels: NATO chief Jaap De Hoop Scheffer condemned an attack on alliance peacekeepers in Afghanistan which killed a Norwegian troop, but vowed that NATO would not be deterred. The alliance's secretary-general said the attack yesterday on a convoy of International Security Assistance Force (ISAF) troops "was an appalling act of senseless violence". One Norwegian soldier was killed in the rocket attack on the convoy as it patrolled along Jalalabad road, the main highway leading into Kabul from the east, and another Norwegian soldier was slightly wounded, ISAF said.
