Islamabad, Pakistan (CNN) -- A NATO jet and helicopters entered Pakistani airspace Tuesday starting an exchange of gunfire between coalition and Pakistani forces, Pakistani officials said.
Two coalition helicopters operating on behalf of U.S. Forward Operating Base Tillman in Afghanistan were fired upon from the Pakistani side of the border between the two countries, a Western military official who asked not to be named told CNN. Asked if the helicopters were on the Afghan side of the border, the military official said they believed so but were not sure.
After being fired upon a second time, the helicopters returned fire, the official said. Authorities later received reports that two Pakistani soldiers were injured, according to the official.
Pakistani officials confirmed that two soldiers were wounded. The Pakistani military said it has lodged a "strong protest" and called for a meeting of the two sides.
A NATO spokeswoman offered little detail about the incident.
"We're aware of a cross-border incident. We're still assessing the situation," said Lt. Commander Kaye Sweetser, a spokeswoman for the coalition troops.
Pakistani intelligence officials said the incident started when a NATO fighter jet entered Pakistani airspace near the border with Afghanistan. This prompted Pakistani troops to begin firing at the jet from the ground, said the officials who did not want to be named because they were not authorized to speak to the media.
The jet retreated and then returned accompanied by helicopters and fired on a military check post in a village in North Waziristan, the officials said.
The incident comes at a time of increased tension between Pakistan and the United States. Pakistani officials have bristled over an unauthorized U.S. raid into Pakistan to kill al Qaeda leader Osama bin Laden. U.S. drone strikes in Pakistan have also been a source of concern, as Islamabad claims the strikes have killed civilians.
The Pakistani parliament recently condemned the raid and adopted a resolution calling for a review of its counter-terrorism cooperation agreement with the United States. The resolution also ordered the immediate end of drone attacks that targets militants in a tribal region of Pakistan near the Afghan border.
U.S. Sen. John Kerry has been visiting Pakistan this week, and said Monday Pakistan will return Tuesday the tail of a U.S. helicopter damaged during the bin Laden raid -- a move aimed at improving cooperation between the two nations.
The helicopter crashed during the raid of the al Qaeda leader's compound May 2. Navy SEALs were able to destroy much of it, but the tail remained largely intact. In photos of the wreckage, numerous aviation experts claim they saw several telltale signs of stealth technology.
