The Islamic State's growing popularity in the Far East could pose a long-term threat, experts warn.
Southeast Asian men are already fighting in the Middle East, according to Nor Asizan Bin Idris, a professor on national security at the National University of Malaysia.
"For now, they are focused on fighting in the Middle East, but in the future they could target Asia," he told Al Jazeera.
Channel News Asia has identified one Islamic Group recruit as 26-year-old Malaysian Ahmad Tarmimi Maliki, who reportedly drove a military vehicle carrying explosives into Iraq's special forces headquarters in Anbar province, killing 25 soldiers and himself on May 26.
In recent months, the Malaysia Royal Police have arrested 15 men for their alleged links to the Islamic State group. One of the suspects was a 30-year-old naval officer who had been in service for 10 years.
In Singapore, the country’s deputy prime minister, Teo Chee Hean, told parliament just last week that a handful of Singaporeans had gone to fight in Syria, adding: "The presence of former foreign fighters in our region - whether they originate from Southeast Asia or elsewhere - is a security threat to us."
One was identified as Haja Fakkurudeen Usman Ali, a naturalised citizen, who left his wife and three children for Syria. Another is a Singaporean woman who joined her husband and two teenage children. Several others were stopped before leaving.
Meanwhile in Indonesia, a prominent preacher serving a 15-year prison sentence at a maximum security facility near Java has also reportedly urged his followers to fight alongside the Islamic State group.
According to the Jakarta Post, Abu Bakar Bashir sent his message of support through the leader of the Jamaah Anshorut Tauhid, a group designated a terrorist organisation by the US. His group has reportedly continued to raise funds to send fighters abroad.
There are at least 50 known Indonesian armed men who have joined the Islamic State group. One 19-year-old fighter identified by Jakarta Post as Wildan Mukahallad, who previously fought in Syria, died in a suicide attack in Baghdad.
"The seeds of quite a few security issues are being sown in Syria and Iraq at the moment," Shanahan, of Australia's Lowy Institute for International Policy,said.
