DERA ISMAIL KHAN, Pakistan >> A NATO helicopter attacked a Pakistani army post near the Afghan border on Tuesday, injuring two soldiers and further increasing tensions following the U.S. raid that killed Osama bin Laden, Pakistani officials said.
A similar event last year in which two Pakistani soldiers were killed prompted Pakistan to close for over a week a key border crossing that NATO uses to ship supplies into landlocked Afghanistan.
NATO coalition spokesman Lt. Col. John Dorrian confirmed there were helicopters flying near the Pakistani border Tuesday and that there was “an incident.” The alliance was investigating, he said.
A Western military official said the incident started before dawn, when a NATO base in Afghanistan received intermittent direct and indirect fire from the Pakistani side of the border.
Two helicopters flew into the area to provide support, one of which fired across the border after twice receiving fire from the Pakistani side, said the official, speaking on condition of anonymity because of the sensitivity of the issue.
The Pakistani army said in a statement that its troops fired on the helicopter after it entered Pakistani airspace in the early hours of the morning. Two of its troops were injured when the helicopter returned fire, it said.
The attack took place in the Datta Khel area of the North Waziristan tribal region. The area is a known sanctuary for Taliban and al-Qaida militants and has been targeted repeatedly by covert U.S. drone strikes.
NATO said it was still trying to determine whether the helicopter crossed in to Pakistani airspace.
“We’re investigating the incident to determine a flight path by examining GPS waypoints in the helicopter computer, to construct a sequence of events and ultimately determine what led to the exchange of fire,” said Dorrian, the NATO spokesman.
He declined to say which coalition country was involved. But most of the helicopters that fly in that part of Afghanistan are American.
Dorrian said NATO will work with the Pakistani government to determine what happened, saying they expect it will reflect the same good cooperation seen in recent military operations along the border. In recent weeks, NATO and Pakistan have launched coordinated offensives against militants on their respective sides of the border.
“This is going to be transparently looked into,” Dorrian said.
The Pakistani army said it has lodged a strong protest and demanded a meeting with NATO officials to discuss the incident.
Last September, a U.S. helicopter attack killed two Pakistani soldiers at an outpost near the Afghan border, prompting Pakistan to close a key border crossing used by NATO for 11 days. The U.S. later apologized, saying the pilots mistook the soldiers for insurgents being pursued across the border from Afghanistan.
Relations are even more tense now following the Navy SEALs raid on May 2 that killed bin Laden in Abbottabad, an army town only about 35 miles (55 kilometers) outside the Pakistani capital, Islamabad.
The Pakistani government is outraged that the U.S. carried out the operation without telling Pakistan first, and many U.S. officials have expressed disbelief that bin Laden could have lived in Abbottabad for at least five years without the authorities’ knowledge. However, the U.S. has also said it has not found any evidence yet that Pakistani leaders knew of bin Laden’s whereabouts.
The helicopter attack comes a day after U.S. Sen. John Kerry wrapped up a 24-hour visit to Islamabad in which he worked to salvage the relationship with Pakistan, but also warned the government that “actions, not words” were needed to get ties back on track. Kerry was the most high-profile American to visit Pakistan since the raid on bin Laden.
Kerry said Pakistan had agreed to immediately take several “specific steps” to improve ties, but did not say what they were. The only tangible signs of progress were a remark by Kerry that Pakistan had agreed to give America the tail of a classified stealth helicopter destroyed by U.S. commandos when it malfunctioned during the raid and an announcement that Secretary of State Hillary Rodham Clinton would soon announce a trip to the country.
But there have also been signs of Pakistan’s anger.
The Pakistani government sent the United States a written request following the bin Laden raid, asking Washington to reduce the number of American military personnel in the country, said a U.S. military official Tuesday, speaking on condition of anonymity because of the sensitivity of the issue.
There are currently more than 200 U.S. military personnel in Pakistan, some of whom are tasked with training Pakistani troops, said the official. Pakistan has asked the U.S. to reduce the number of trainers in the country, but the official would not specify the numbers involved.
Also Tuesday, Pakistani security forces shot and killed four would-be suicide bombers, including three women, when they tried to attack an army checkpoint in the southwestern city of Quetta, said Daood Junejo, the city police chief. A fifth suicide bomber detonated his explosives but did not injure anyone, the police chief said.
Security forces stopped the five as they approached the checkpoint in a car, said Junejo. One of the men got out of the car and blew himself up. The other four, who were also wearing suicide vests, were shot when they tried to lob grenades, he said.
However, local TV footage showed what appeared to be security forces shooting at two of the women as they were laying on the ground, one of them with her hand raised over her head.
