The Malaysian police have arrested nine suspected Islamic State (Isis) militants, including two who are thought to behind a grenade attack at a bar in Kuala Lumpur in June. The country's police chief confirmed the arrests on Saturday (13 August).

Muhammad Wanndy Muhammad Jedi, a Malaysian fighter in Syria with allegiance to IS (Daesh) had claimed responsibility for the 28 June attack, on his Facebook page. The grenade explosion at a bar in the western Malaysian town of Puchong had left eight wounded. The police are still believed to investigating the authenticity of the claim. If proved genuine, it would be the first attack in Malaysia by the terrorist group.

Khalid Abu Bakar, inspector-general of police, said two men who carried out the attack on the bar, were arrested when they were waiting to get instructions from Wanndy about future attacks, Reuters reported.

"Following on from their arrest, police managed to seize a grenade, and it was suspected it would have been used in a planned attack," Khalid said in a statement.

A 17-year-old from the eastern state of Sabah is believed to be one among the nine detained militants. He was reportedly an IS sympathiser, who was planning a lone wolf attack on non-Muslims after getting in touch with a Malaysian militant in Syria.

Two others were also arrested for reportedly harbouring the suspected IS duo, while one more person suspected to have IS links was tracked down by the police. Khalid said the suspect received an order from Wanndy on his mobile with a message to attack the police headquarters in Kuala Lumpur and government buildings in the country's administrative capital of Putrajaya.

Khalid added that three foreign nationals, who were ex-military men, were arrested in Kuala Lumpur for reportedly using the Muslim-majority country as a transit point while they obtained forged travel documents to carry out planned attacks in the Middle East.

According to reports, there are 200 Malaysians among the 230 people the police have arrested since 2013 for their alleged links to the militant group and its activities.
