More than 100 people have died in ethnic clashes in Karachi in five days of violence, officials in Pakistan said. Karachi police official Naeem Shah reported three deaths Saturday as clashes between two political parties, the Muttahida Qaumi Movement and the Awami National Party, escalate, CNN reported. Pakistan's Dawn News said the death toll from the latest round of fighting has left at least 102 people dead in the last five days. The Sindh government Friday authorized police to "use necessary force to prevent terrorist acts." Dawn said at least 13 people were killed in overnight gunfire. At least eight shops were burned in the Alibarh Colony Friday, while a commercial center in Kharadar met the same fate. "We are moving the families to safe places and the exercise continues. Rangers troops helped mainly people in Qasba Colony and adjoining areas," a Sindh Ranger said. Violence between the two factions has left hundreds of people dead in recent years, CNN said.
