The Congress and the BJP were engaged in a bitter war of words on Friday over some sensational claims made by former RAW chief AS Dulat on Gujarat riots and hijacking of IC-814 from Kathmandu. A Special Advisor on Kashmir in Atal Bihari Vajpayee’s PMO, Dulat, in his book titled — Kashmir: The Vajpayee Years — has commented on several contentious issues, including Gujarat riots, Kandahar hijacking, and Vajpayee’s visit to Srinagar in April 2003 when he famously extended his hand of friendship towards Pakistan.
