Congress MP Shashi Tharoor recalled how PM Narendra Modi invited Pakistani officials to probe 2016 Pathankot airbase attack. Tharoor said PM Modi, who had made a goodwill visit to Pakistan recently, had called then-Pakistan PM Nawaz Sharif, asking the country to join the investigation. Pakistani investigators visited the airbase, went back and claimed, 'Indians did to themselves', Tharoor said.
