IS galvanized in Asia by Philippine city siege, report says

JAKARTA, Indonesia -- The attack by Islamic State groupaffiliated militants on a Philippine city has galvanized its Southeast Asian supporters and spells trouble for the region, a top terrorism researcher said Friday as the occupation of Marawi nears two months despite a sustained military offensive.

In a new report, Sidney Jones, an expert on militant networks in Southeast Asia at the Jakarta-based Institute for Policy Analysis of Conflict, said there now may be a higher risk of attacks in other Philippine cities and cooperation between militants across regional borders could expand. Militants in Indonesia and Malaysia will want to redouble efforts to attack police and may also lift their sights to targeting foreigners, she said.

“The initial photographs from Marawi released over social media as the ISIS assault began — smiling fighters hold guns aloft on trucks — seemed to have the same impact as the iconic ISIS victory photos from Mosul in 2014,” Jones said, using another acronym for IS and referring to its past occupation of Iraq’s second-largest city. “They generated a shared sense of triumph and strengthened the desire of ISIS supporters in the region to join the battle.”

Waving IS-style black flags, the heavily armed fighters stormed into Marawi, a center of Islamic faith in the south of the predominantly Roman Catholic Philippines, on May 23, occupying buildings, houses and mosques and taking hostages. Foreign fighters, including 20 Indonesians, joined the insurrection, which officials and researchers say received funding locally and from IS in Syria that was coordinated by a Malaysian known as Mahmud bin Ahmad.

At least 565 people, including 421 militants and 99 soldiers and police, have been killed have been killed in the worst urban uprising by Muslim militants in the volatile southern Philippines in decades. Nearly half a million residents have been displaced in Marawi and outlying towns by the fighting.

Jones said Indonesians and Malaysians who joined the fight in Marawi could return to their countries, and with their high prestige provide new leadership, uniting factionalized proIS cells.

But a Malawi-style attack in Indonesia, the world’s most populous Muslim nation, is unlikely because unlike the southern Philippines, it does not have the multiple insurgencies that extremists can draw on for fighters and weapons, she said.

The report was based on research in the southern Philippine region of Mindanao, interviews with Indonesian militants, credible news reports including from The Associated Press and monitoring of pro-IS groups on the Telegram instant messaging app.

When the militants holding out in Marawi are defeated, the rebuilding of the city, which
