MANILA - (UPDATED) State troops neutralized an Islamic State-linked straggler in Marawi early Tuesday, a week after the government ended the 5-month terror rampage there, the military said.

The male straggler was killed in a gun battle after after he attempted to escape from the main battle area around 6 a.m., Col. Romeo Brawner, deputy commander of Task Force Ranao, told ABS-CBN News.

No soldier was wounded in the incident, said Brawner.

The government declared an end to the hostilities in Marawi last October 23, when leaders of the Islamic State-linked fighters were killed in a fierce final stand.

The fighting has taken a heavy toll, reducing buildings to skeletons of mangled steel and rubble, and killing more than 1,100 people, mostly extremists.

Some 6,500 families are due to return this week in a phased repatriation, a fraction of the 77,000 that fled to evacuation camps or nearby towns. Many face a lengthy wait for vast swathes of Marawi to be rebuilt.
