Several gunmen opened fire at a political rally Tuesday in Karachi, Pakistan, leaving 10 people dead and 29 wounded, police said.
Police suspect the gunmen belonged to a rival political party, Karachi Police official Naeem Shah said.
Some of the victims were bystanders, police said.
Pakistani TV showed images of a gunfight between police and the attackers, which lasted several hours.
The video showed scores of people frantically running for cover and victims' grief-stricken relatives sobbing at local hospitals.
At least 20 vehicles and six area shops were burned.
Police said by Tuesday night they had the situation under control, but that they had yet to make any arrests.
Karachi has long been plagued by gang violence fueled by supporters of political parties vying for power in Pakistan's commercial hub.
Officials say low pay and a lack of manpower and resources put police at a disadvantage against criminal gangs that are often armed with automatic weapons.
Turf wars in Karachi killed more than 1,000 people last year, many of them innocent bystanders who were caught in crossfire, according to Pakistan's human rights commission.
