At least thirty people were killed as two NATO helicopters struck northwest tribal area of Pakistan bordering Afghanistan on Monday morning. Local media reports say the Afghanistan-based NATO helicopters fired at the militants hiding in the Pakistani side who earlier launched an attack at a NATO check post in the Khost area of Afghanistan. But the report failed to say when the check post was attacked by the militants. Most of the people killed in the incident were believed to be militants. So far there is no response yet from the Pakistani government regarding the incident.
