MARAWI, Philippines - Saripada Pacasum Jr. gagged and turned away the first time he came across a decomposing body in Marawi, where hundreds have died since Islamic State-inspired fighters attempted to overrun the southern Philippines town six weeks ago.

But the rescue and recovery volunteer had no time to waste as gunfire rang out from government troop positions and militant snipers around him: he put on a pair of rubber gloves and helped carry the remains out of the conflict zone in a pickup truck.

"I thought of resigning after that," said Pacasum, who works in a disaster relief office. "I was scared and not prepared for this kind of job."

But Pacasum, 39, continued to lead a team of about 30 young men and women who make near-daily forays to rescue civilians and retrieve victims in an urban battlefield that is infested with rebel snipers and battered by airstrikes.

They have come to be known as the "white helmets" or "suicide squad" because of the risks they take when going in unarmed and wearing little protection other than white plastic construction helmets.

Internal security threat

More than 460 people have been killed since the battle for Marawi began on May 23, including 82 members of the security forces and 44 civilians.

The military believes hundreds of civilians are still trapped by the conflict, the biggest internal security threat the Philippines has faced in decades and a shock to neighboring countries worried that the IS group is trying to establish a foothold in Southeast Asia.

Fishermen, farmers, students and small business owners, mostly from Marawi, are among those who have volunteered for rescue missions.

"We all grew up in Marawi and it breaks our hearts when we hear that Marawi is under siege," said AbdulAzis Lomondot Jr., a 25-year-old university student, speaking in the team's one-room office in the town's capitol complex where many of the "white helmets" grab some sleep.

The team has received counseling and equipment from the International Committee of the Red Cross, and training on how to properly handle cadavers.

Pacasum, who has led more 10 rescue missions, wants to see the battle through to the end, but will consider changing professions when it's over.

"It's too stressful, he said.

"Some of the volunteers ... they are just young kids, they are very aggressive. I'm more cautious. I have kids and I want to watch them grow old."
