KARACHI - In order to avoid any untoward incident during Muharram-ul-Haram, the Sindh government has imposed ban on pillion riding from Friday (today). DIG South Commander Shaukat said the Sindh Home Department will impose a ban on pillion riding from Friday to lessen the threat of terrorism. He said pillion-riding is banned every year during Muharram because chances of terror attacks are higher. In the recent past, a wave of ethnic violence has claimed dozens of lives in Karachi, paralysing the commercial hub of the country. At the centre of the bloodshed are Orangi and Qasba Colony, considered to be among the biggest slums in South Asia, with mixed population of Pashtuns and Mohajirs. The Mohajir and Pashtun ethnic parties traded blames on each other for stoking the violence, labelling each other as terrorist.
