The Taliban were conducting a bomb-making class for a number of their fighters in northern Afghanistan when a bomb accidentally exploded killing 30 of their own fighters including a number of foreigners. 

The incident took place at 9.15 a.m. on Saturday morning in the Qultac village of the Dawlat Abad district of Balkh province, the Afghan defense ministry said. The province is located about 280 north of the capital Kabul and borders Uzbekistan.

“This incident happened as a number of Taliban… had gathered for mine-making training,” the ministry added.

The Khaama Press News Agency reported that the foreigners were “expert mine makers” according to the 209th Shaheen Corps of the Afghan military.
