Islamabad: Pakistan on Thursday rejected as 'baseless' India's assertion that the Gurdaspur attackers had infiltrated from there, saying such 'provocative' comments are a threat to regional peace and security and asked India to share concrete evidence before pointing fingers.

"The Government of Pakistan categorically rejects the baseless allegations made by Mr Rajnath Singh, Home Minister of India, in the Parliament, today," Foreign Ministry Spokesman Qazi Khalilullah said in a statement in Islamabad. He said Pakistan regrets the 'unsubstantiated and unwarranted assertion' that those involved in the Gurdaspur incident of 27 July, had entered India from Pakistan.
