An explosion inside a mosque in Northern Afghanistan on Thursday killed 11 people during the funeral service for an Afghan acting provincial governor who was assassinated earlier in the week, officials say.

The blast occurred in Faizabad the capital of Badakhsan, an Afghanistan province that shares borders with China and Tajikistan.

About 30 people were also injured by the blast according to the Taliban-run Ministry of Interior which condemned the attack in a statement.

“The Ministry of Interior of the IEA condemns this brutality of the disgraced enemies,” the statement by the Ministry of Interior reads.

The funeral was in memory of Nisar Ahmad Ahmadi, a Taliban provincial deputy governor who was killed by a suicide bomber on Tuesday.

IS claimed responsibility for the attack which saw a suicide bomber drive a car filled with explosives close to Mr Ahmadi’s car. The suicide bomber detonated the explosives leading to the death of Mr Ahmadi and his driver.

The assassinated deputy governor was being laid to rest at the mosque when an explosion went off, killing 11 people and injuring over 30 people in the mosque.

Former Afghan president Hamid Karzai took to Twitter to condemn the Thursday blast at the mosque. He labelled the attack an act of “terrorism” which is “against human and Islamic standards”. He also conveyed his condolences to the affected families.

Taliban security forces have sealed off the scene of the attack, mounting checkpoints on roads that lead to the mosque.

The Taliban administration has often carried out raids on members of the Islamic State which have claimed responsibility for various attacks in the country.
