Washington: Singapore's Defence Minister said on Wednesday that Islamic State fighters pose a "clear and present danger" to Southeast Asia as they return from Syria and Iraq with a mission to establish a caliphate.
Defense Minister Ng Eng Hen also said al Qaeda linked groups such as Jemaah Islamiyah and Abu Sayyaf are posing an added threat to regional security by pledging allegiance to IS.
He said that in the past three years, IS and its ideology have attracted more followers in Indonesia, Malaysia and Singapore than al Qaeda drew in the 10 years after the September 11 attacks in the United States.
Malaysia has reported up to 150 foreign fighters going to Iraq and Syria, including some from the Malaysian armed forces, Indonesia has reported more than 500 and a few have traveled from Singapore, Ng said.
"The returned fighters have come back with allegiance to ISIS and the mission to form an Islamic caliphate in our part of the world," Ng said, using an alternative acronym for the Islamic State group.
"They have sympathizers, they have foreign fighters who are trained, who have the motivation, the means, and who have a common vision," he said.
He stressed the importance of intelligence-sharing among countries in the region to address the threat, while expressing concern that followers of Qaeda-linked groups in Southeast Asia that had pledged allegiance to IS would now link up.
In the years after September 11, 2001, members of the Jemaah Islamiyah network plotted attacks in Southeast Asia, particularly in Muslim-majority Indonesia, where the 2002 Bali bombings that killed 202 people, mostly foreign tourists.
The Abu Sayyaf militant group has remained an active but diminished force in the southern Philippines.
Ng spoke at an event organized by the Center for a New American Security, a Washington think tank.
