A bomb killed 11 people in a poor district of Pakistan's financial hub of Karachi on Wednesday, mostly teenagers playing street football at a crowded market, officials said.
.
The sweltering port of 18 million people is largely inured to violence with a dozen bodies 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,'' said resident Zafar Baluch.
.
It was unclear who was behind the blast in the Lyari district, a stronghold of the main opposition Pakistan People's Party.
.
Karachi is home to many militant groups, including the Taliban. Many political parties there have armed wings to fight turf wars.
