Terrorists who now use the internet to conduct their activities present a major challenge to Association of Southeast Asian Nations (ASEAN) countries, said Malaysian Defence Minister Mohamad Sabu. 

Increasingly rapid technological advancements had created a borderless world, he said, and terrorists were using this medium to learn and create new terrorism tools.

"We have determined that terrorists are now using the internet as a medium to learn how to make explosives, and previously, a woman has been arrested in Kuala Lumpur for making bombs from the internet.”

"So, all the ASEAN security forces must give attention to steps to tackle this threat of terrorism,” he told reporters.
