"If we can attack this side, the other side could also be attacked," he said in Urdu. He also tweeted in English: "You (Indian Prime Minister Narendra Modi) are the killer of hundreds of Muslims. We wl take the revenge of innocent people of Kashmir and Gugrat (sic)."
Prime Minister Narendra Modi has been briefed about the incident by his security advisors although the authenticity of the Tweets could not be verified. Intelligence agencies believe that the Wagah border was a clear message that the Taliban group's next attack would be in India. Incidentally, a terror threat rocked the Kolkata port, forcing the Navy to remove two of its warships from the eastern side.
61 people died on the Pakistani side at the Wagah border when a suicide attack ripped the parade ground where the Pakistani flag was being lowered at sunset.
TTP-JA, the terrorist outfit that masterminded the attack, had broken away from mainstream Taliban movement in September and had declared its support for the IS in Syria and Iraq.
