NATO helicopters attacked a military checkpoint in northwest Pakistan on Saturday, killing up to 28 troops and prompting Pakistan to shut the vital supply route for NATO troops fighting in Afghanistan, Pakistani officials said.
The attack comes as relations between the United States and Pakistan, its ally in the war on militancy, are already badly strained following the killing of al Qaeda leader Osama bin Laden by U.S. special forces in a secret raid on the Pakistani garrison town of Abbottabad in May.
Pakistan called that raid a flagrant violation of its sovereignty.
The Foreign Office condemned Saturday
