Muttahida Qaumi Movement (MQM) chief Altaf Hussain on Saturday urged the government to address the demands of Quetta blast victims’ families at earliest. He added that the elements responsible for such attacks were open enemies of humanity. The MQM chief also expressed grief over no response from the provincial authorities towards the protesters who continued their sit-in along with victims’ bodies on Alamdar Road. Altaf urged the government to ensure the protection of life and property of the people and bring the perpetrators of the blast to book.
