We'll claim the pilots weren't sure of where the border was while in hot pursuit. Whether that's true or not is probably irrelevant, because we'll have to say it.

Yeah, but I'm not interested in what our public stance is. I'm wondering what really occurred.

MIRANSHAH, Pakistan (Reuters) - A U.S. helicopter gunship mistakenly strayed into Pakistani territory from Afghanistan while chasing militants and wounded three civilians in an attack, a Pakistani security official said on Saturday.

Villagers in Pakistan's North Waziristan tribal region on the Afghan border said one person was also killed in the Friday night raid but the region's security chief said no one was killed.

"The helicopter entered Pakistan due to a navigational error," the security official, Mehmood Shah, told Reuters. "Three civilians were injured."

U.S. forces are not allowed to conduct combat operations inside Pakistan.

Villagers said the helicopter fired on a van, wounding the three, than made a second attack in which one person was killed. Body parts had been found at the scene of the second attack, they said.

Pakistani forces have been battling al Qaeda and other rebels in its wild tribal border lands in recent days while U.S. forces on the Afghan side have mounted their own offensive against the militants.
