ISLAMABAD (AP) — A government official says gunmen opened fire in a commercial market in Pakistan's largest city, killing 11 people.
The Tuesday night attack was the latest in a spasm of violence to hit Karachi and underscore the poor state of security in the U.S. allied nation.
Government official Sharmila Farooqi says 51 people, including several political activists, have been killed in the city since Saturday.
Because of its status as the country's main economic hub, keeping Karachi calm is of prime importance to Pakistani leaders who have seen criminality soar alongside Islamist militant violence.
A major chunk of supplies for U.S. and NATO troops is shipped to the city before traveling overland in Pakistan and into neighboring Afghanistan.
