More than 60 people are believed to have been killed, with up to 180 injured in a bomb blast that decimated a busy market in a Shia Muslim quarter of the Pakistani city of Quetta on Saturday.
Authorities said the attack is believed to have been carried out by Sunni Muslim extremists who regularly target Pakistan's estimated 20 million Shias, according to AP.
Wazir Khan Nasir, deputy inspector general of police in Quetta, told: "The explosion was caused by an improvised explosive device fitted to a motorcyle. This is a continuation of terrorism against Shias."
