Pakistan troops 'repel US raid'

Pakistani troops have fired warning shots at two US helicopters forcing them back into Afghanistan, local Pakistani intelligence officials say.

The helicopters flew into the tribal North Waziristan region from Afghanistan's Khost province at around midnight, the reports say.

Tensions have risen after an increase in US attacks targeting militants.

The incident comes amid mounting security fears after a militant bomb attack on the Islamabad Marriott hotel.

Pakistan's army has said it will defend the country's sovereignty and reserves the right to retaliate to any border violations.

The government has said it will take targeted action against the militants, promising raids in some "hotspots" near the border with Afghanistan.

The latest confrontation between US and Pakistani forces took place in North Waziristan's sparsely populated Ghulam Khan district, west of the main town in the region, Miranshah, local officials say.

They told the BBC that troops at border posts in the mountainous region fired at two US helicopters which crossed into Pakistani territory.

The helicopters returned to Afghanistan without retaliating.

A senior security official based in Islamabad told the AFP news agency that the helicopters had been repelled by both army troops and soldiers from the paramilitary Frontier Corps (FC).

"The helicopters were heading towards our border. We were alert and when they were right on the boundary line we started aerial firing. They hovered for a few minutes and went back," the official said.

"About 30 minutes later they made another attempt. We retaliated again, firing in the air and not in their direction, from both the army position and the FC position, and they went back."

A Pakistani military spokesman, Maj Murad Khan, said he had no information "on border violation by the American helicopters".

The US military in Afghanistan also said it had no information on the incident.

The BBC's Barbara Plett in Islamabad says after increased American incursions this month, the army stressed that it reserved the right to retaliate.

Our correspondent says standard procedure would be to first fire warning shots.

Comment:

I'm not sure how much credence to give this. The sources are either local or anonymous, and the governments of both nations deny it— unlike the ground assault earlier this month. On the other hand, the politics of the situation are extremely complicated, and it may well be that the two governments are trying to minimize the incident in public while duking it out behind closed doors.

What it really comes down to, though, is the description of the event itself. We are fully aware that Pakistan has troops stationed along the border. I find it to be unlikely that our method of getting past these troops would be to bumble around in helicopters.
