According to sources, two security officials were injured in a shelling strike by Nato helicopters in Datta Khel. 
MIRAMSHAH: A Nato helicopter from Afghanistan  intruded into Pakistan’s North Waziristan region on Tuesday, wounding  two troops, local intelligence officials said, adding to tensions  between Islamabad and the West.
“It happened early  morning,” a Pakistani intelligence official in the region, who declined  to be identified, told Reuters. “The helicopter hit a Pakistani check  post on the border in the Datta Khel area.”
Another  intelligence official said several Pakistani helicopters took off from  Miranshah, the main town in North Waziristan, towards the site of the  attack. The purpose of the Pakistani mobilisation was unclear.
The Pakistani military was immediately unavailable for comment.
Lieutenant-Commander  Colette Murphy, a spokeswoman for the Nato-led International Security  Assistance Force (ISAF), said in Kabul that the coalition was aware of  the reports and looking into them, but had no immediate comment.
North  Waziristan is the base of the Haqqani network blamed for the insurgency  in eastern Afghanistan. US-led drone aircraft have repeatedly targeted  the area over the past year.
Many militants, including foreign  fighters loyal to al Qaeda, are based in Datta Khel. It is a stronghold  of fighters loyal to Hafiz Gul Bahadur and has been a frequent target of  US drone strikes.
Pakistan’s private news channel said the  checkpost targeted in the latest attack was located right on the border  between Afghanistan and Pakistan.
It quoted officials as saying  that the helicopters were just about to intrude into Pakistani territory  when aerial gunshots were fired. They subsequently moved back but fired  a retaliatory shot due to which rubble fell from the nearby mountains  and wounded the security personnel.
The reported incursion came a  day after unmanned US drone aircraft fired missiles in Datta Khel  killing 12 militants, Pakistani officials said.
An intelligence  official said that one of the dead militants, an Arab, was the son of an  al Qaeda operative identified as Abu Kashif. There was no way to verify  the death toll. Militants often dispute official accounts of drone  attacks.
Relations between the US and Pakistan have been pushed  almost to the breaking point after the secret May 2 raid on Abbottabad  that killed Osama bin Laden, embarrassing and humiliating the powerful  Pakistani Army and intelligence service.
Before that, in late  January, undercover CIA contractor Raymond Davis killed two Pakistanis  in Lahore, resulting in a six-week standoff over diplomatic immunity.
A  previous incursion on Sept. 30, 2010, killed two Pakistani troops and  wounded four more when Nato helicopters crossed the border while pursing  insurgents. Pakistan retaliated by shutting down the supply route for  Nato troops in Afghanistan.
Washington sees the rugged border  region between Afghanistan and Pakistan as a critical battleground  against al Qaeda and the Taliban.
