KARACHI, Pakistan -- A bomb killed 11 people, mostly teenagers playing street soccer, at a crowded market in Karachi, Pakistani officials said early Wednesday. 

The sweltering port of 18 million people is largely inured to violence -- around a dozen bodies are found around the city every day -- but the killing of so many youngsters shocked many residents. 

"There was total chaos when the bomb went off. People were screaming and running for safety," resident Zafar Baluch said. 

It was unclear who was behind the blast in the Lyari district, a stronghold of the main opposition Pakistan People's Party but Karachi is home to many militant groups, including the Taliban and many political parties there have armed wings to fight turf wars.

The attack appeared to be aimed at a provincial minister, Javed Nagori, who had come to hand out prizes at the soccer match, provincial information minister Sharjeel Memon said.

The teens had been playing while their parents shopped. 

"There was smoke everywhere and people were covered in glass," said Sheree, who didn't want to give her last name. She was near Nagori's convoy when the blast knocked her off her feet. She saw the bodies of three children, she said.
