Union Shipping Minister GK Vasan has instructed Chairmen of all the three Major Ports in Tamil Nadu -- Chennai, Tuticorin and Ennore -- to take all precautionary measures and to be "fully alert", a release from Chennai Port Trust said.
Accordingly, extra deployment of security personnel have been made at each entry and exit points from both land and sea to prevent any untoward incident.
Moreover, CISF QRT (Quick Reaction Teams) and Marine Commandos have also been directed for patrolling in the respective areas round the clock, it said, adding, CISF' Intelligence Wing was in touch with security agencies.
Security has been stepped up in the state following an alert from the Intelligence Bureau last week that terrorists plan to sneak in through the Palk Strait from Jaffna in Sri Lanka and attack Madurai and Mayiladuthurai.
It was further strengthened when an anonymous phone call claimed of an infiltration.
