Aiyar, who was suspended by the Congress late last year after his "neech" slur against Prime Minister Narendra Modi, has again created a row, saying: "I receive much more hatred in India than the love I receive in Pakistan. I am really happy to be here."
Aiyar's comments came days after Pakistan-based terrorists on February 10 killed six persons in an attack at Sunjawan army base camp in Jammu region.
Defence Minister Nirmala Sitharaman on Monday said: "Pakistan will pay for this misadventure."
"I don't believe the governments will change anything, but I believe in you people," he said.
"People here, who in 1965 and 1966 -- after the Tashkent Declaration -- were running after the leader who said India and Pakistan will fight for a 1,000 years, are now welcoming me and clapping for me because I talk of peace. This deepens my trust in Pakistan," he said.(ANI)
