A bomb blast as fans left a football stadium in Karachi on Tuesday night killed at least 11 spectators and injured dozens more. Most of the casualties are reported to be children.

Inside World Football said the bomb, which contained ball bearings to inflict the maximum damage, was situated deliberately to target fans as they filed out of the ground.

"When the match ended, we came out and as soon as we came out there was a blast," Ameer Ali, who was injured in the blast, told Reuters. "Everyone started running in panic. Many people were hit, which scared everyone."

Speaking to AFP FIFA referee Ahmed Jan said: "Football is dying. It died, maybe, for the last time on Tuesday. If the government fails to maintain law and order soon then I'm afraid this sport's most loving part of the city will not be there on the sporting map."

The match was between two teams named after a local gang leader who earlier in the year was accused of beheading a rival and then using his head as a football.
