Parts of the Arabian Sea port city have become battlegrounds with authorities struggling to stem the violence, blamed on activists from political parties representing competing ethnic groups, from spiralling. The independent Human Rights Commission of Pakistan says 800 people, most of them poor, have died since January, including 300 last month alone. Much of the violence has been blamed on tensions between supporters of the Muttahida Qaumi Movement (MQM), rooted in the Urdu-speaking majority, and the Awami National Party (ANP), which represents ethnic Pashtun migrants. The human rights commission says the violence in Karachi is the deadliest since 1995, when more than 900 killings were reported in the first half of the year. Interior Minister Rehman Malik told reporters the other day in Karachi that the government had taken steps to clear out stockpiles of illegal weapons by cancelling all firearm licences at the end of the month, forcing owners to reapply. At present some licence holders have illegally acquired hundreds of weapons on a single licence, which will end next month, said Malik. From September anyone caught with a weapon with the old licences will be dealt with seriously. Such people could be tried in anti-terrorism courts and get sentences of seven to 14 years, he added.
