The Norwegian military says four of its soldiers have died after a roadside bomb exploded near their vehicle in northern Afghanistan.
A military statement says the soldiers were killed while on a mission in Faryab province on Sunday evening. The military has not specified the nature of the mission.
The Defence Ministry says the soldiers were part of a stabilization force in the province. The ministry says this is the highest number of Norwegian troops killed in a single attack since the start of the war. Until Sunday, only five Norwegian troops had been killed in the entire war.
Norway has about 500 troops stationed in Afghanistan.
