Pakistan on Sunday rejected Indian charges that morphed pictures of Assam and Myanmar violence which sparked an exodus of northeastern citizens from other states originated in Pakistan.
Such remarks only widen the trust deficit between the two countries, sources in the Pakistan high commission here said.
Home Secretary RK Singh said on Saturday that the bulk of rumours of imminent attacks on northeastern people for the killings of Muslims in Assam originated in Pakistan.
The rumours forced thousands to flee Karnataka, Maharashtra and Tamil Nadu.
The Pakistani sources said these were "cooked up" charges.
"Instead of indulging in mud-slinging and blame game, it's time for India to address its internal issues," the source told IANS. "Such comments only widen the trust deficit.
Singh had said India will take up the issue with Pakistan. "I am certain they will deny our information but our technical team is very certain of the information it has gathered," he said.
