Police sources said that inputs have been received from central security agencies that there might be a terror attack in Kolkata, especially in the port area. Amidst this warning, Navy warships – INS Khukri and INS Sumitra which had docked at the port and was scheduled to be there till November 6 for public viewing as part of Naval Day celebration, made a sudden withdrawal today. However, official sources in Delhi said, the withdrawal was a precautionary measure. PTI reports quoting the defence sources said the withdrawal of the ships were due to operational reasons.

Meanwhile, the Pentagon has told the US Congress in its latest six-monthly report that Pakistan is using militant groups as proxies to counter the superior Indian military. It said, Afghan-and Indian-focused militants continue to operate from Pakistan territory to the detriment of Afghan and regional stability. These relationships run counter to Pakistan's public commitment to support Afghan-led reconciliation and such groups continue to act as the primary irritant in Afghan-Pakistan bilateral relations.

India has welcomed Pentagon reports that Pakistan is using terrorists to counter Indian army. External Affairs Ministry spokesman Syed Akbaruddin said in New Delhi that if international community is acknowledging the fact that terrorism derives support from Pakistan, it is something that New Delhi welcomes. He said, India is of the view that terrorists should not be segmented.
