An explosion in northern Afghanistan killed 15 people at a religious school in an alleged attack that the Taliban have labeled as an "unforgivable crime." 

"This is the handiwork of the enemies of the people of Afghanistan who target innocent people and children," Suhail Shaheen, the Taliban's permanent representative of Afghanistan to the United Nations, told Fox News Digital. "No doubt, their true nature is revealed to the world and to the Afghan people through their gruesome and horrendous acts."

"All those individuals or entities who help them carry out such tragic incidents are complicit in this crime," he added, saying that "in retrospect, ISIS is behind such tragic incidents."

The blast occurred at around 12:45 p.m. – the time of afternoon prayers. Initial reports indicated that 10 people had died, but the number rose to 15 within a few hours, with at least 20 others injured in Wednesday’s blast, Al Jazeera reported.

The U.S. State Department did not respond to a Fox News Digital request for comment by time of publication. 

No one has claimed responsibility yet for the attack on the school in Afghanistan’s Samangan province, but an Afghan affiliate of the Islamic State has waged a campaign of violence against the new government since its takeover in Aug. 2021.
