RAWALPINDI/ PAKISTAN: A North Atlantic Treaty Organisation (NATO) aircraft infiltrated Pakistan's airspace on Wednesday and flew around for a duration of five to six minutes, Express News reported.
They were in breach of Pakistan's laws, reported Express News.
Later, military sources contradicted the news saying that no such incident had occurred.
They said there was no question of airspace violation by the coalition forces aircraft operating in Afghanistan.
Earlier, an airstrike on Pakistani border posts in November 2011 in the Salala area of Mohmand Agency had killed two dozen Pakistani border guards, an event that had sunk the Pakistan-American relation to an all-time low.
United States blamed the cause of the incident on mistakes made by both sides.
NATO helicopters had pounded a Pakistani checkpost for hours despite attempts by Pakistani troops to communicate with the NATO forces that they were friendly forces.
