At least 15 people have been killed in northwestern Pakistan in a raid involving helicopters used by foreign troops in Afghanistan, security officials said.
"Four gunship helicopters from across the border carried out the raid," a top security official told AFP news agency.
Habib Khan Wazir, a witness, said the incident happened after a US helicopter landed outside a house in the village of Musa Nikow in South Waziristan before dawn on Wednesday.
He said the troops came out and fired on people outside and inside a house.
Two local intelligence officials confirmed the account on condition of anonymity. One official said 19 died.
Bombing in Swat
Earlier on Tuesday, Pakistani military jets bombed an area in the nearby Swat valley killing at least 10 people and wounding dozens, a security official said.
The bombing came despite an offer of truce during the current Muslim fasting month of Ramadan announced by the government at the weekend.
A senior security official said fighter jets bombed Ghat Peochar area following intelligence that leaders of pro-Taliban cleric Mullah Fazlullah's group were hiding there.
"We are not sure if any leader was among 10 killed in the air strike," the official, who spoke on condition of anonymity, told AFP news agency.
Major General Athar Abbas, the military's chief spokesman, confirmed the bombing but said he did not have details of casualties.
Fazlullah's spokesman, Mulsim Khan, earlier on Tuesday claimed to be holding two Chinese telecoms engineers and their entourage who were kidnapped four days ago from neighboring Dir district.
He claimed the latest air strike killed only civilians and that none of the group's fighters were hurt.
The engineers went missing along with their local driver and a security guard near the Afghan border where they had been checking an installation.
