QUETTA - Two Pakistani nationals were shot dead by Nato forces on Thursday in Afghan province of Helmand, which borders with Chagai district. According to Levies Force sources, two persons, namely Muhammad Usman and Abdullah, resident of Chagai, had gone to Bibijani area of Helmand in Afghanistan to visit their relatives, when personnel of Nato forces opened indiscriminate fire on them. As a result, both sustained critical wounds and succumbed to their injuries on the spot. However, the relatives of deceased had not received bodies of the deceased till filing of this report. It may be mentioned here that people belonging to both sides of border frequently visit their relatives as they have blood relations. I can confirm that the bodies of two residents of Chagai have arrived from Afghanistan, Chagai Assistant Commissioner Tufail Baloch told news agencies. But I do not have any information on how they were killed. It happened on Afghan soil so we dont have many details yet. Pakistani border guards said NATO forces may have been responsible for killing the two Pakistanis. The officials said the two men were gathering wood. They said NATO helicopters fired on their vehicle. Agencies add: Seven Pakistani workers were kidnapped in an area near the Afghan capital Kabul, police said Thursday. The Pakistanis - engineers and workers assigned to a hospital construction project in Logar province - were returning to their accommodation after work when they were snatched at gunpoint on Wednesday. They were going home from work. Along the road, their minivan was stopped by unknown gunmen, their driver was forced out of the car and all were taken away to an unknown location,Logar police chief Ghulam Sakhi Roghliwani said. The abduction comes as Pakistans relations with Afghanistan and the United States are at a low after cross-border Nato airstrikes killed 24 Pakistani troops on Saturday. Weve launched a search operation. We hope to find them and free them very soon, said Roghliwani. There was no claim of responsibility for the abduction but police said the kidnapping might have been carried out by 'criminal gangs seeking a ransom.
