PESHAWAR: A bomb destroyed three music and video shops and partially damaged seven others in the regional headquarters of the North Waziristan Agency days after militants circulated pamphlets warning against selling such goods. The bomb went off in Garhi Mandi at 1:00am on Friday a day after the government had banned the public display of firearms and launched a disarmament drive. No casualties were reported as streets were deserted at the time of the explosion. "It is too early to point a finger at any group or anybody," the official said. Militants, linked with Al Qaeda and Taliban, distributed hand-written leaflets in Miranshah earlier this week telling hotels and music shops to stop showing television and selling DVD movies within five days or face the consequences. "You (shopkeepers) will be responsible for any damage if our message is not taken seriously," the pamphlets read. Many of damaged shops sold TV sets, audio and videocassettes and rented out music and movie CDs. Former US forces commander in Afghanistan Lt Gen David Barno told reporters in Islamabad that Pakistan would launch a spring offensive in North Waziristan, but Islamabad denied.
