More than 100 girls and women have come forward with new sexual abuse accusations against United Nations peacekeepers in the Central African Republic, the UN revealed on Thursday.

The accusations included allegations that a French military commander forced three girls to indulge in sexual relations with a dog, an accusation that the world body describes as shocking to the core.

These new revelations dramatically expand an already alarming scandal involving troops sent to protect civilians in the world’s hotspots, who became predators instead.

U.N. spokesman Stephane Dujarric said 108 alleged victims of sexual abuse have been interviewed by a U.N. team in Kemo prefecture, east of the capital Bangui, the vast majority of them minors.

The allegations date from 2013 through to 2015, and now eclipse the former 22 allegations of sexual abuse and exploitation in the C.A.R.

The United Nations has been in the spotlight for months over dozens of allegations of child rape and other sexual abuses by its peacekeepers, especially those based in Central African Republic, which has faced sectarian violence since 2013. There have been similar allegations against the French force known as Sangaris, which operates independently in the country, known as CAR.

Secretary-General Ban Ki-moon said he was “shocked to the core by the latest allegations,”

“Yesterday, the Central African Republic inaugurated a new democratically elected President, marking the end of a transition period,” he said. “The interventions of the international community helped save the CAR from an unspeakable fate. Yet we must face the fact that a number of troops who were sent to protect people instead acted with hearts of darkness.”
