At least 100 people have been killed and wounded after a suicide bomb attack tore through in Afghanistaninfo-icon's northeastern Kunduz province on Friday, as per reports. 

"Our initial findings show that it is a suicide attack," Matiullah Rohani, director of culture and information in Kunduz, told news agency AFP.

Further, Dost Mohammad Obaida, the deputy police chief for Kunduz province, said that the "majority of people there have been killed."

If confirmed, the death toll of dozens would be the highest since USinfo-icon and NATO forces left Afghanistan at the end of August and the Taliban took control of the country.

Taliban spokesman Zabihullah Mujahid had earlier said an unknown number of people had been killed and injured when "an explosion took place in a mosque of our Shiite compatriots" in Kunduz.

Video footage showed bodies surrounded by debris inside the mosque that is used by people from the minority Shi'ite Musliminfo-icon community.

Zalmai Alokzai, a local businessman who rushed to Kunduz Provincial Hospital to check whether doctors needed blood donations, described horrific scenes.

"I saw more than 40 dead bodies," he told AFP. "Ambulances were going back to the incident scene to carry the dead."An international aid worker at the MSF hospital in the city told AFP there were fears the death toll could rise.

"Hundreds of people are gathered at the main gate of the hospital and crying for their relatives but armed Taliban guys are trying to prevent gatherings in case another explosion is planned," he said.

Kunduz's location makes it a key transit point for economic and trade exchanges with Tajikistaninfo-icon.

It was the scene of fierce battles as the Taliban fought their way back into power this year.

Often targeted by Sunni extremists, Shiite Muslims have suffered some of Afghanistan's most violent assaults, with rallies bombed, hospitals targeted and commuters ambushed.

Shiites make up roughly 20% of the Afghan population. Many of them are Hazara, an ethnic group that has been heavily persecuted in Afghanistan for decades.
