At least 14 people died and 22 others were wounded Sunday in a bomb attack on security forces in the tribal area of North Waziristan, in northwestern Pakistan, authorities told Efe.

The bomb went off around midday in the town of Miransha and the target appears to have been a vehicle of the Frontier Corps, or FC, Pakistan's paramilitary border protection force, a member of the local administration said.

An official for the coordinating agency for the tribal zones based in the nearby city of Peshawar said that 14 people had been killed in the attack, but he did not specify precisely how many were members of the FC although he said that "many" of them were.

Military sources quoted by the local daily Dawn confirmed that all the dead were members of the FC and added that 25 people had been wounded.

According to the newspaper, the injured were transported to Peshawar for medical care.

North and South Waziristan are the main redoubts of Pakistan's Taliban movement and other Muslim fundamentalist organizations that launch attacks on both sides of the border, in both Afghanistan and Pakistan.

Those two areas are the zones in which U.S. drone aircraft principally operate to harass the militant insurgents who stage operations against NATO forces deployed in Afghanistan. EFE
