establish a Southeast Asian caliphate as they suffer battlefield defeats in Iraq and Syria.
"Mahmud remains... one of our high-value targets in the operations being conducted," military

On Tuesday, the military said it raised the alert level in a part of the southern Philippines
as it warned against retaliatory attacks from sympathizers of the militants.
The directive included tightening border security to prevent militants from moving around the

military's final push in Marawi.
"The US Government will continue to work with the Armed Forces of the Philippines in the final
phases of this operation, and looks forward to cooperating in assuring the stabilisation and
rehabilitation of Marawi," US embassy press attache Molly Koscina told AFP.
