Two NATO helicopters killed 30 insurgents on Pakistani soil after a rare manned pursuit violated the border, NATO forces said on Sunday.
The two Apache attack helicopters from the NATO-led International Security Assistance Force (ISAF) violated the border from eastern Afghanistan on Friday after the insurgents attacked a remote Afghan security outpost in Khost province.
ISAF spokesman Sergeant Matt Summers confirmed that the helicopters had attacked after crossing into Pakistan.
He did not comment on which countries’ forces were involved, but the United States is the only coalition member that uses Apaches.
ISAF said in a statement issued late on Sunday that the helicopters were following its rules of engagement when they crossed into Pakistan.
Two Kiowa helicopters returned to the area on Saturday and killed at least four more insurgents, the statement said.
ISAF was not immediately able to confirm whether the Kiowa helicopters had also crossed the border. US forces make up the majority of ISAF troops in Afghanistan’s east.
