The perpetrators of Gurdaspur terror attack came from Pakistan via Ravi river, Home Minister Rajnath Singh said in Parliament on Thursday.

The home minister made the statement on the terror attack in Punjab's Gurdaspur district on 27 July amid ruckus created by the members of Congress, who shouted slogans in the Rajya Sabha.

"Terrorists who attacked Gurdaspur came from Pakistan via Ravi river," Singh said citing hints from global positioning system (GPS).

The minister said the government is committed to give a "befitting reply to those who try to undermine India's security". "Any terror activity from across the border will be defeated," he said.

However, unsatisfied by the home minister's statement, Congress MPs continued to disrupt the proccedings in the upper house. The house was finally adjourned for the day amid uproar.
