A US drone aircraft missile attack targeting a militant camp in Pakistan killed at least four people and wounded three.
Officials said the drone fired four missiles as dusk fell on Baghar, a village in the mountains 55 km 35 miles west of Wana, the main town in the region.
Foreigners were among the fighters staying in the tents by the spring that runs through Baghar.
US commandos raided the nearby border village of Angor Adda on September 3, and another helicopter-borne raid there was aborted on Monday after Pakistani troops and villagers opened fire, according to Pakistani officials.
The attack came after a senior US military commander promised to respect Pakistan's sovereignty while fighting terrorists along its Afghanistan border.
US-Pakistani co-operation will be developed on "issues that challenge the security and wellbeing of the people of both countries,'' the US embassy said, citing comments by Admiral Michael G. Mullen a day after Pakistan demanded that the U.S. and NATO stop raids on its soil.
Admiral Mullen, chairman of the US Joint Chiefs, spoke during a meeting with Prime Minister Yousuf Raza Gilani today in Islamabad. The US has said Pakistan hasn't done enough to combat Taliban and al-Qaeda terrorists regrouping in the Pakistani tribal region on the border.
Pakistan's military said Afghan-based forces led by the US were behind a Sept. 3 attack that killed seven civilians near the border with Afghanistan.
The US declined to confirm or deny the operation; NATO denied responsibility.
Pakistan said 11 of its soldiers died June 10 in a US air strike on a Pakistani frontier post. The Bush administration said the strike targeted militants who had crossed into Afghanistan.
