The exercise, third of its kind since the start of ISPS code implementation at Chittagong Port, lasted for two hours from 10am that saw hectic security check-up at the port's jetty gates and other protected areas to ensure safety.

CPA earlier declared 'security level-2' at the port meaning heightened state of security in and around the port area, port officials said.

Talking to The Daily Star, Director (Security) of CPA Sarwar Shaheed said, "We have arranged the mock exercise to test the alertness of officials concerned and port security personnel in case of any threat of terrorist act in this port."

"We have got a tremendous response from all officials and port security personnel and we will hold more such exercises for them in future," he added.

The ISPS code is being implemented in the port following instruction from International Maritime Organisation to all of its member ports to comply with the security code against the backdrop of September 11 attacks on America in 2001.

Chittagong Port Authority trained up its personnel and stepped up security measures in and around the port's protected areas to foil any attempt of terrorist acts, officials said.
