At least 47 people were killed and 70 others wounded after several explosions tore through a Shiite mosque during Friday prayers in the Afghan city of Kandahar, the Associated Press reported quoting a Taliban official. Pictures from inside the Bibi Fatima mosque show shattered windows and bodies lying on the ground and other worshippers trying to help. There was no immediate claim of responsibility for the carnage. A local Taliban official told AFP news agency it was a suicide bombing. Hafiz Sayeed, the Taliban’s chief for Kandahar’s department of culture and information, said 47 people had been killed and at least 70 wounded in the attack. Taliban spokesman Bilal Karimi earlier reported 32 dead and 68 wounded. Witnesses said they saw three attackers -- one detonating a device at the main door and two inside the mosque. Murtaza, who and like many Afghans goes by one name, said he was inside the mosque during the attack and reported four explosions: two outside and two inside. Friday prayers are the busiest congregation of the week, and the building was full of worshippers at the time. At least 15 ambulances were at the scene afterwards, an AFP journalist said. Another witness, also named Murtaza, was in charge of security at the mosque and said he saw two bombers. He said one detonated explosives outside the gate, and the other was already among the worshippers inside the mosque. He said the mosque’s security personnel shot another suspected attacker outside. Video footage showed bodies scattered across bloodstained carpets, with survivors walking around in a daze or crying out in anguish. Taliban special forces have secured the site and have asked people to donate blood to help the victims, Reuters reports. BBC Afghanistan correspondent Secunder Kermani says that IS-K, a local branch of the Islamic State Group, is expected to say it was behind the blasts. Kandahar is Afghanistan"s second largest city and the spiritual birthplace of the Taliban, so an attack in the city by IS-K, which is extremely hostile towards the Taliban, would be significant. Last Friday, a suicide attack on another Shia mosque during Friday prayers in the northern city of Kunduz killed at least 50 people. IS-K said it carried out the attack, which was the deadliest since US forces left at the end of August. IS-K, a Sunni Muslim group, is the most extreme and violent of all the militant groups in Afghanistan. It has targeted Afghan security forces, politicians and ministries,and religious minoritie
