Dera Ismail Khan: Intelligence officials say a roadside bomb struck a military convoy in Pakistan`s South Waziristan tribal area near the Afghan border, killing three soldiers.
The officials say Monday`s attack in the Ladha area of South Waziristan also wounded four soldiers. The bomb was detonated by remote control and destroyed one military vehicle.
The officials spoke on condition of anonymity because they were not authorised to talk to the media.
South Waziristan was the main sanctuary for the Pakistani Taliban before the military launched a large ground offensive in October 2009. But attacks against security forces have continued in the area.
