At least 30 Taliban militants have died in Afghanistan after they blew themselves up during a bomb-making class.
The blast happened on Saturday morning at a mosque in the village of Qultaq in the Dowlatabad district of Balkh province.
The bodies of the six foreigners could not be identified because of the extent of the damage caused by the explosion, the army statement revealed.
The militants had gathered to learn techniques for making bombs and IEDS from the six foreigners, who were reportedly considered experts in the subject.
The Islamic State group's local affiliate has claimed responsibility for some of the attacks, but many go unclaimed, with the government putting the blame on the Taliban.
In eastern Ghazni province, the provincial governor's spokesman, Wahidullah Jumazada, said an airstrike called in during fighting with the Taliban killed at least 22 insurgents, including foreign fighters in the group.
Taliban spokesman Zabihullah Mujahid immediately tweeted a denial, saying Afghan government forces were defeated in the fighting in Ghazni. »
