The Pakistani military fired on US helicopters as they attempted to cross the border in Pakistan’s Taliban-controlled tribal agency of North Waziristan, according to reports from the region. The latest US incursion comes just two days after a suicide bombing destroyed the Marriott Hotel in the heart of Islamabad. A little-known terror group took credit for the strike.

As usual, it’s tough to know who, if anyone, is telling the truth.

“There was no such incursion; there was no such event,” Colonel Gary Keck, a Defense Department spokesman told The Associated Press.

Pakistani military forces flew repeated helicopter missions into Afghanistan to resupply the Taliban during a fierce battle in June 2007, according to a U.S. Marine lieutenant colonel, who says his information is based on multiple U.S. and Afghan intelligence reports.

You really should read the whole thing. A lot of the claims are based on observations by Afghan intelligence, and even if true it’s not clear that Pakistani forces are operating under official orders.
