The siege in the Philippines has escalated after eight civilians were found in a ravine shot dead by militants linked to Islamic State.
Rebel gunmen stopped the civilians, believed to be carpenters, as they tried to escape the violence in Marawi City, according to police.
They were killed because they could not cite verses of the Quran, Marawi police officer Jamail C Mangadang said.
Police found the bodies had been shot in the head, some with hands tied behind their backs, and a sign was tied to the one of the bodies that said “munafik” (traitor).
