NATO provided no other details about the deaths, including the nationalities of the troops. The coalition normally waits for member nations to disclose those details, according to the AP.
The roadside bomb struck a police vehicle traveling through the Qadis district of the northwestern province of Badghis, the provincial governor's spokesman, Sharafudin Majedi, told the AP.

There was no immediate claim of responsibility, but roadside bombs are regularly planted by Taliban insurgents fighting a decade-long war against NATO-led foreign troops and Afghan government forces, according to Agence France-Presse.
The deaths come one day after a man wearing an Afghan army uniform shot and killed a US soldier in the Kunar province of northeast Afghanistan.
As of Friday, at least 1,834 members of the US military had died in Afghanistan as a result of the US-led invasion in late 2001, according to an Associated Press count.
