A high alert has been sounded in the coastal areas of Kerala after intelligence agencies warned about the movement of 15 suspicious ISIS terrorists in the Indian Ocean region.

Intelligence agencies said as many as 15 Islamic State terrorists have set sail from Sri Lanka to the Lakshadweep islands to save themselves from raids conducted by the Sri Lankan police in the aftermath of the serial bomb blasts in the island nation.

The local administration has alerted the fishing vessels and others venturing into the sea to be cautious of suspicious activities, reports said.
