Some reports, attributed to Pakistani officials, said the dead included two Qaeda commanders, identified as Abu Majid al-Iraqi and Sheikh Abu Waqas. Other reports said four Uzbek militants had died.

“The Pakistan Air Force does not generally undertake stand-alone strikes such as these because it is not equipped with the appropriate strike weapons,” a Pakistani military source said.

The American narrative of those strikes is very different.

Two senior United States officials said there had been no American involvement in the attacks. A third official said the C.I.A. had not paid the reports much attention because no American forces had been involved. But that official said American intelligence pointed to the Pakistan Air Force as having conducted the first strike, probably as part of a military operation against Pakistani Taliban militants in the neighboring Orakzai tribal agency.

The second attack was more mysterious. “It could have been the Pakistani military,” the official said. “It could have been the Taliban fighting among themselves. Or it could have been simply bad reporting.”
