Amnesty International on Tuesday accused United Nations peacekeepers of raping a 12-year-old girl and killing a boy and his father during an operation in Central African Republic's capital Bangui earlier this month.

The U.N. mission, set up to maintain stability as the country struggles to emerge from two years of inter-religious violence, was already facing allegations of abuse, as are French soldiers and a previous African peacekeeping force.

The incidents evoked by Amnesty occurred on Aug. 2 and 3 following an armed clash between soldiers from the MINUSCA mission and residents of Bangui's PK5 Muslim enclave in which one Cameroonian soldier was killed and nine others were injured.
