According to Pakistan government officials, the NATO aircraft violated Pakistani airspace in Lawara Mandi, Datta Khel, Ghulam Khan and Saidgi areas, close to Pak-Afghan border around 11 pm on Monday night. Both the aircraft flew over these areas for about 25 minutes and returned to the Afghan side of the border without any action, the officials said. Pakistan has been repeatedly protesting against the intrusion of its air space by US-led NATO forces. Even last week, a NATO aircraft hovered over Pakistan's territory for a few minutes before landing back in Afghanistan. Prior to this, more such incidents had taken place.
