KANDAHAR: Suicide bombers attacked a Shia mosque in the southern Afghan city of Kandahar during Friday prayers, witnesses said, killing at least 41 people and injuring scores more.

The assault came just a week after a suicide attack on Shia worshippers at a mosque in the northern city of Kunduz, which was claimed by the Islamic State group.

There has not yet been any claim of responsibility for the attack in Kandahar, the spiritual heartland of the Taliban.

"Our initial information shows it was a suicide bomber who blew himself up inside the mosque. We have launched an investigation to find out more," a local Taliban official told AFP.

Hafiz Abdulhai Abbas, director of health for Kandahar, told AFP: "Information from the hospitals shows 41 killed about 70 wounded in today's mosque attack."
