Source (AP) Pakistan forced an Indian military helicopter to land Sunday for violating its airspace near the disputed border with Kashmir and briefly took its four-member crew into custody, Pakistani military officials said. India said the helicopter veered off course because of bad weather, and Pakistan allowed the aircraft to return soon after the incident. Pakistan and India are rival nuclear powers who have fought three wars since gaining independence from Britain in 1947. The relationship has improved somewhat in recent months, especially regarding trade, but there is still significant distrust on both sides. The helicopter was intercepted about 12 miles (20 kilometers) inside Pakistani territory, said a Pakistani military official, speaking on condition of anonymity because of the sensitivity of the issue. It was forced to land near Skardu, a town in Gilgit-Baltistan that is close to K2, the second highest mountain in the world, said Pakistan army spokesman Maj. Gen. Athar Abbas. Skardu is about 60 miles (100 kilometers) north of U.N.-drawn Line of Control separating Kashmir into areas controlled by Pakistan and India. India said the helicopter strayed across the Line of Control because of bad weather and landed in Pakistan-controlled Kashmir, according to a statement on the Ministry of External Affairs website. The three pilots and their crew chief were taken into custody but were later allowed to return home with their helicopter, said Abbas. Two of the three wars between Pakistan and India have been fought over Kashmir, a disputed Himalayan territory. Both countries claim all of Kashmir.
