JOHANNESBURG (AP) — A new United Nations report says South Sudan government troops and allied fighters killed at least 232 civilians in a five-week period this year, with some victims hung from trees and others burned alive.

The U.N. report released Tuesday is the latest snapshot of the widespread atrocities committed in the world's youngest nation over its five-year civil war. It says the "deliberate, ruthless" attacks may amount to war crimes.

Human rights monitors found at least 120 women and girls were raped or gang-raped between April 16 and May 24. Others who resisted were shot dead.

More than 30,000 people were displaced in opposition-held areas in Leer and Mayendit.

The U.N. human rights chief says "there must be consequences for the men who reportedly gang-raped a 6-year-old child, who slit the throats of elderly villagers."
