KARACHI  - Traffic police in the Pakistani city of Karachi said Thursday they have launched a campaign to stop music being played in public transport due to complaints from women.

Drivers caught playing music will be fined and music players will be confiscated.

The authorities denied the move was in response to a reported warning from the Taliban, who consider music sinful.

"No there was no threat to the traffic police from anyone, it is entirely baseless," Arif Hanif, Karachi traffic police chief AFP. "We only got complaints from the women commuters and nothing else," Hanif said.

"And the campaign is aimed at implementing the law, as rules prohibit playing music in public transport," he said.

Congested roads of the chaotic city of 20 million are plied by a variety of public transport vehicles including buses, rickshaws and taxis.
