MARAWI, Philippines (Dispatches) -- Security forces traded heavy gunfire with Daesh militants inside a southern Philippine city Monday, as fears grew for up to 2,000 people unable to escape a week of fighting that has left women and children among the dead.
President Rodrigo Duterte imposed martial law across the southern third of the Philippines shortly after the fighting erupted, warning the gunmen were involved in an effort by Daesh to set up a local caliphate.
But street-to-street battles and a relentless military bombing campaign has so far failed to end the crisis in Marawi, one of the biggest Muslim cities in the mainly Catholic Philippines, and authorities expressed alarm about the fate of those trapped.
"They are texting us and calling us for help," Zia Alonto Adiong, spokesman for the provincial crisis management committee, said of the 2,000 people his office had recorded being unable to leave areas held by the militants.
"They can't leave because they are afraid of running into checkpoints put up by the gunmen."
Authorities said the gunmen had already murdered at least 19 civilians, including women and children, while 17 members of the security forces had died in the clashes and 61 militants were killed.
Eight bodies were found Sunday morning dumped off a bridge on the outskirts of Marawi, which is normally a bustling city of 200,000 people known as a center of Islamic culture and education.
Most of the city's residents had fled to nearby towns. But adding to the fears for those who remained, the military announced on the weekend that it would intensify a bombing campaign on the areas being held by the militants.
When asked Monday about fears of civilians being bombed, military spokesman Brigadier-General Restituto Padilla told reporters that airstrikes would be done with precision.
However he said the bombings would continue in whichever areas the militants were hiding.
The violence began when dozens of gunmen went on a rampage throughout Marawi in response to an attempt by security forces to arrest Isnilon Hapilon, a veteran Filipino militant regarded as the local leader of Daesh.
