Hawzah News Agency - No group has claimed responsibility but the government is accusing Taliban insurgents of carrying out the attack.

Villagers searched for the bodies of their loved ones on Saturday in the rubble of a mosque in eastern Afghanistan that collapsed in a blast during Friday prayers, killing 70 people including dozens of children, officials said.

The attack – the country's second most deadly this year – took place in Haska Mina district of eastern Nangarhar province and also wounded at least 36 people.

"We have reports that the death toll has reached 70 in yesterday's incident," the provincial governor's spokesman Attaullah Khogyani told AFP.
