Philippines President Duterte claims ISIS leader ordered attack on Marawi

US troops providing "technical assistance," but Duterte denies he asked for help

CNN  — 

Bombs continue to shake the southern Philippines city of Marawi as the battle to eradicate hundreds of ISIS-affiliated militants enters its third week.

As the fighting wears on, deadline after deadline set by the Philippines government for the end of the conflict has been missed, including a pledge to finish the fighting by Monday, the country’s Independence Day.

A presidential spokesman said Saturday it would take at least two more weeks to clear the embattled city.

CNN Philippines correspondent David Santos, who is currently less than five kilometers from the fighting, said the progress of government forces has been slowed by concerns over civilians caught in the crossfire.
