How Pakistan shot down India's cutting-edge fighter using Chinese gear

ISLAMABAD/NEW DELHI, August 2 (Reuters) -Just after midnight on May 7, the screen in the Pakistan Air Force's operations room lit up in red with the positions of dozens of active enemy planes across the border in India. Zaheer Sidhu had been sleeping on a mattress just off that room for days in anticipation of an Indian assault. New Delhi had blamed Islamabad for backing militants who carried out an attack the previous month in Indian Kashmir, which killed 26 civilians.
