Karachi (PPI) - Chairman Sindh National Front (SNF) Mumtaz Ali Bhutto expressed concerns over deteriorating law and order situation in Sindh and demanded resignations of rulers on recent Karachi violence which claimed over 50 lives. In a statement issued here on Saturday, he said the recent ethnic violence in Karachi exposed the claims of Sindh Chief Minister Syed Qaim Ali Shah regarding prevalence of peace in the Sindh province, as over 50 people lost their lives in these ethnic riots in Karachi alone, while over 100 sustained serious injuries. He said important government officials in India resign on Mumbai mayhem and bombing incidents, but over the Karachi violence issue, Pakistani rulers were only issuing formal statements instead of following the suit of their Indian counterparts. Mumtaz Bhutto blamed Pakistan Peoples Party for massacre of Sindhis by making coalition with the MQM in 1988 and said that coalition had resulted in killings of people of Interior Sindh living in Karachi to earn livelihood. He claimed that political terrorists had challenged government writ in Karachi but the propaganda was being aired regarding so-called Talibansation in the City. He said rulers neither could provide roti, kapra aur makan as promised in its election menifesto to people, nor security to their life and property.
