Azlan said the move was among border enforcement mechanisms which should be refined so that monitoring could be done more effectively.

However, he said the border wall should be equipped with high-level security features to prevent breaching of the wall.

Azlan said border intrusion would continue to occur if the parties concerned only relied on the existing system in view of the current challenges in border enforcement.

“Border intrusion is nothing new. In fact, the issue of human trafficking and the discovery of more than 100 mass graves in the border area also stemmed from the same problems.

“This (border intrusion) is not an easy thing (to curb)… many other aspects also need to be streamlined, for example we have to take into account the mountainous border areas which are covered mostly by thick forest,” he told Bernama.

He was commenting on a newspaper report over the condition of the security fence in the duty-free zone at Bukit Kayu Hitam, Kedah that was increasingly critical due to intrusion.
