DHAKA: A high alert has been sounded at the Kolkata Port, with central agencies warning of a terror threat on Tuesday, reports NDTV. 

Two Indian Navy warships, INS Khukri and INS Sumitra, that had docked at Kolkata for Navy week celebrations, have gone back to sea. A Defence Ministry statement said they had been "withdrawn for undisclosed operational reasons."
 
The warships were scheduled to be anchored in Kolkata till Friday, and were to be opened to the public on Wednesday and Thursday.

Intelligence sources said after some intercepts suggested that there was a terror threat to the Kolkata port, the West Bengal government held a high-level security meeting with central agencies, the Army and the Navy and decided to sanitise the port.

The coast guard and other agencies have been alerted.
 
Though the alert is for the Kolkata Port, the dock complex in Haldia has been put on alert.
