"This is not communal violance, this is a war between Pakistan and India, whatever is happening there is Pakistan-inspired," he told reporters outside Parliament.
He said the violence was perpetrated against the locals, their houses and shops burnt, Pakistan flag was unfurled and pro-Pakistan slogans were raised but the "government remained a mute spectator as the events unfolded. It is trying to hide the truth".
The clashes broke out on Eid day and spread to other parts of the Jammu region including Jammu city and Rajouri town.
Sinha also demanded a probe into Robert Vadra's land deals, claiming the "fraud" into the deal was committed on a large scale.
"This is an issue of a fraud on a large scale...This is a violation of all the laws and Robert Vadra has presented to this country and rest of the world a unique business model where you don't invest anything and end up making huge profits," he told reporters outside Parliament.
Whistleblower IAS officer Ashok Khemka has alleged that Vadra, son-in-law of Congress President Sonia Gandhi, "falsified documents" for 3.53 acres of land in Gurgaon and "pocketed" large premium on a commercial colony license.
