WANA, Nov 29: Two soldiers were critically injured in a bomb blast near an army outpost in the Hamrang area close to the Afghan border, some 25 kilometres west of the South Waziristan Agency headquarters on Tuesday.

The injured soldiers, who belonged to a unit of the Azad Kashmir regiment, were taken to Wana and later to Peshawar for medical treatment.

Meanwhile, troops have mounted a search for the attackers and raided several hideouts in the troubled tribal agency.

They captured three suspects and shifted them to an undisclosed location for interrogation, sources said.

Troops have also started construction of new bunkers in the tribal agency to reinforce their positions against foreign and local militants.

For the last three to four days, soldiers had been constructing new bunkers and fortifying the existing ones, sources said.

On the other hand, a tribal band of Taliban has renewed their activities. Its members can be seen roaming in the main bazaars and streets in the agency, openly brandishing lethal weapons and forcing tribesmen to strictly follow Islamic injunctions.
