The parents of two US Marines said their sons were left traumatised after being asked to clean up the mess. One of the men, Lance Corporal Roel Ryan Briones, said he had taken photos quickly confiscated by investigators and carried bodies out of homes.

"They ranged from little babies to adult males and females," he said. "I'll never be able to get that out of my head. I can still smell the blood."
