The Pakistani military said it shot down an Indian spy drone on Wednesday in Kashmir, in a new sign of the decades-old tension between the nuclear-armed rivals in the disputed region.Industry experts said the small, unarmed model was sold commercially for aerial filming and would contain no secret military technology."An Indian spy drone was shot down by Pakistani troops which intruded into Pakistan along (the Line of Control) near Bhimber today. The spy drone is used for aerial photography," a statement from the Pakistani military said.The Indian military was not available for comment.Bhimber is in Kashmir, the Himalayan region claimed by both Pakistan and India. The two sides regularly exchange fire along Kashmir's heavily-militarized Line of Control.A photo supplied by the Pakistani military appeared to show a Chinese-made DJI Phantom 3, said Huw Williams, the Unmanned Systems Editor at IHS Jane's International Defense Review."Due to its limited operating range - about two km - if the Indian military is using the system it would most likely be for close reconnaissance or security work," Williams said.
