Pakistani troops, Coalition helicopters trade fire near Afghan border

Pakistan's army says its troops fired warning shots when two helicopters crossed the Afghan border and that the helicopters returned fire before re-crossing the frontier. The US-led coalition has confirmed that its helicopters were fired on Thursday, but denies that its aircraft crossed the border or fired back. A Pakistani military issued a statement insisting the helicopters passed over one of their border posts and were "well within" Pakistani territory when the troops fired what it called "anticipatory warning shots." It said it was in contact with NATO's headquarters in Kabul and that the issue was being resolved.
