Islamabad , Pakistan ( CNN ) -- A blast targeting Shiites in a busy Pakistani marketplace killed at least 78 people on Saturday , police told CNN . The attack in the southwestern Pakistan city of Quetta left at least 180 people wounded . The explosives were packed into a parked water tanker and were remotely detonated , said Mir Zubair Mehmood , a senior police official in Quetta . The South Asian nation , overwhelmingly Sunni , has been beset by sectarian strife and attacks for years . Mehmood said the attack targeted a Shiite Hazara community . Ethnic Hazaras live mostly in Afghanistan , and there are also Hazara enclaves in Afghanistan and Iran . President Asif Ali Zardari and Prime Minister Raja Pervez Ashraf strongly condemned the bombing and vowed to go after the militants . Earlier this year , a wave of attacks in Quetta left 87 people dead in the Shiite community .
