Islamic State threat in Southeast Asia raises alarm in Washington

WASHINGTON — Southeast Asia’s jihadis who fought by the hundreds for the Islamic State group in Iraq and Syria now have a different battle closer to home in the southern Philippines. It’s a scenario raising significant alarm in Washington.

The recent assault by ISIS-aligned fighters on the Philippine city of Marawi has left more than 300 people dead, exposing the shortcomings of local security forces and the extremist group’s spreading reach in a region where counterterrorism gains are coming undone.
