Director General Military Operations Major General Ashfaq Nadeem has rejected Natos offers of carrying out joint investigation into the Nato raid on Pakistans military checkposts in Mohmand Agency. During a media briefing on Tuesday, he said that there was no outcome of such joint probe into the past attacks. He reiterated that the Nato deliberately attacked Pakistani checkposts and continued targeting them for hours. It was an open aggression and unprovoked attack, he added. The DG MO said it would premature to say anything about motives behind the attack.
