A pair of suicide bombers attacked an army camp in northwestern Pakistan Wednesday, killing at least three soldiers and wounding more than 20 others.
Security officials say the attackers rammed their vehicle packed with explosives into a gate at the camp in Wana, the main town in the South Waziristan tribal area. There was no immediate claim of responsibility.
South Waziristan is one of Pakistan's seven federally administered tribal agencies. The military has launched several offensives in the region targeting the Taliban and militants linked to al-Qaida who have strongholds in the porous border area.
