No one has claimed initially responsibility but considering their past actions in the area the Taliban and other Sunni Muslim extremist groups were suspected to be involved. This was confirmed later. A Jundullah spokesman said it carried out the attack because it considered the victims “kafir” or non-Muslim. Prime Minister Muhammad Nawaz Sharif has condemned the attack and ordered an investigation. Pakistan is about 20% Shia and 70% Sunni. Ismaili Shias, in common with other Shia Muslims revere Ali, son-in-law of the Prophet Mohammed, but they also revere the Imam Ismail who died in 765 AD. Around 100 other people were killed this year in similar attacks.
