Officials in northeastern Afghanistan say unidentified gunmen have kidnapped five aid workers, including two foreigners.

A spokesman for the governor of Badakhshan province said Wednesday the kidnapping happened a day earlier as the group was traveling on horseback in the Yaftal area.

The identities of the aid workers and their organization were not immediately identified.

Badakhshan is not known as a focus of insurgent activity, but militants have carried out attacks in the province.

Last month, a group of Taliban insurgents ambushed a police post, killing at least four police officers and capturing 16 others.

In 2010, the Taliban claimed responsibility for the killing of 10 Christian medical workers, whom it accused of acting as spies and missionaries.
