PESHAWAR, Jan 29: Pakistan had to warn off an American helicopter which violated its airspace above its northern border with Afghanistan, the military said on Sunday.

“It was a technical violation,” Pakistani military spokesman Major General Shaukat Sultan told AFP of the incident which happened on Friday night during US anti-insurgent operations in eastern Afghanistan.

“After warnings from Pakistan side the helicopter went back,” he said.

Two shells were also fired on Friday night from the Afghan side of the border which landed in North Waziristan but there were no casualties, the general said.

The incidents came some two weeks after a US missile attack on a Pakistani village near the Afghan border killed 18 people.—AFP
