Pakistan, Jan 25 (ANI): Pakistan has suspended buses carrying Shi'ite pilgrims from travelling through Baluchistan to Iran due to security concerns after a suicide attack killed at least 27 pilgrims, officials said, as mourners buried their dead. Earlier, a suicide bomber drove his car into a bus killing 27 Shi'ite pilgrims and prompting hundreds of Hazaras to take to the streets to protest against the violence. The leaders of the Hazara Shi’ite community in Quetta called off their protest later after two union ministers, including Interior Minister Chaudhry Nisar Ali Khan, met with protestors and vowed to launch a ‘targeted operation’ against militants targeting the Shi’ites.
