Cambodians threw rice on the ground on Tuesday to mark the 'Festival of the Dead' or Pchum Ben and feed the spirits of the dead.
Cambodians visit pagodas across the country during the 15-day festival that takes place annually to offer prayers and food to the spirits of their deceased relatives, who they believe only emerge to eat the food during this period.
For many, it is a time to remember the victims of the 1975-1979 Khmer Rouge regime.
At least 1.8 million Cambodians - about a quarter of the population - were killed by the Khmer Rouge. Most of the victims died of starvation, torture, exhaustion or disease in labor camps or were bludgeoned to death during mass executions.
