U.S., Pakistan to Conduct Joint Investigation Into Border Clash That Killed Pakistani Troops

The United States says it will conduct a joint investigation with Pakistan of an airstrike along the Afghan border that Pakistan says mistakenly killed 11 of its soldiers.

A senior U.S. diplomat said Friday that the two countries have agreed to look into the matter together in hopes of preventing anything similar from happening again. U.S. Secretary of State Condoleezza Rice expressed regret over the deaths when she met in Paris with Pakistan's foreign minister.

But the U.S. is not ready to say it did anything wrong, and some U.S. officials have disputed Pakistan's account of Tuesday night's incident. The U.S. says coalition forces in Afghanistan bombed militants in the area that night.
