LAHORE: Twin low intensity bomb blasts hit a CD market in Pakistan’s eastern city of Lahore  wounding four people and creating havoc in the area, police said.

Police said the target of the blasts was one of the busiest music and CD markets in the city centre’s Hall Road.

Shopkeepers in the area said they had received threatening letters for selling Western movies and “objectionable CDs” from unknown persons describing the business as “dirty”.

“Four people have been wounded in these two blasts. The target was the CD and music market,” Rafiullah, a police officer at the site who goes by one name,

Sajjad Bhutta, the city’s top administrative official, told reporters at the scene that the bombs were timed devices.

Mudasser Javed, an injured shopkeeper, said he and others like him had received threatening letters warning them to put a stop to the “un-Islamic” business.

TV footage showed shopkeepers closing down their stores and running from the scene soon after the blasts.
