• The Philippines declared an end to months of warfare against Islamic State-inspired militants in the city of Marawi.

But ISIS remains in the Philippines — and is forcing some surprising alliances. South of Marawi, Moro Islamic Liberation Front members, above, are working with their former enemy, the army, against what could become the next big ISIS uprising. U.S. officials, assessing why so few foreign ISIS fighters in Iraq and Syria seem to be returning home, say that many are dead or captured, but that some may have escaped to the Philippines.

The U.S. defense secretary, Jim Mattis, is in the country for today’s meeting of Asean defense ministers, which is expected to be dominated by terrorism, disputes in the South China Sea, and North Korea.
