“Those of you in Bukit Aman, you will no longer have peace. We will slaughter you... when we return. Our friends back home will hunt you down.”

This is the grim warning from terror network Islamic State in its latest propaganda video released on Tuesday, which featured a Malaysian who is fighting in Syria as well.

The graphic video showed him, along with two IS combatants, decapitating three captives.

Bukit Aman’s Special Branch-Counter-Terrorism Division chief Ayob Khan Mydin Pitchay told the New Straits Times the man had been identified as Mohd Rafi Udin from Negri Sembilan.

In the video, Rafi urged IS supporters to employ whatever means necessary to kill non-believers.

“Kill them wherever you meet them... If you have a car, hit them...

“Use your weapons and knives to stab them in the chest,” he said, adding that he and his friends in Syria would lend them support from afar.

Meanwhile, Ayob said his division had discovered two lone-wolf attacks.

He revealed this included a 16-year-old student in Kedah, who was armed with a 27cm knife and a fake pistol, and had targeted a 27-year-old sales assistant.

“The boy had received orders from a Malaysian IS senior to carry out the attack... so he took a knife and tried to kill her just because she is a non-Muslim.

“We also stopped a suspect with two Rambo knives at an LRT station in Jalan Jelatek,” he added.

Ayob also that it would be common for attackers now to use traditional weapons instead of guns or bombs, which he pointed out made it easier to plan attacks undetected.

He disclosed that his division had crippled nine planned attacks by IS supporters, with three of this already in stage two of planning.

The latest propaganda video urged for attacks on governments it has labelled as “Toghut” (sinners/those against the teachings of Allah).

Malaysia has been singled out by the group as a nation that must be fought.

Meanwhile, the video featured Rafi, an Indonesian and Filipino simultaneously beheading three men suspected of being spies.

“We are slaughtering these murtad (apostates), and tomorrow, our brothers in your land will slaughter you... We will use the language of swords and bullets. We will continue to fight and wage war against you, terrorise you and put fear in your hearts,” said the Filipino.

Earlier, Rafi said the person whom IS supporters should look up to was one Abdallah al-Filipini, from the Philippines, who had been appointed to be the leader for Asia.
