Patrice-Edouard Ngaissona and Alfred Yekatom have been sentenced for war crimes and crimes against humanity.

The International Criminal Court has convicted two leaders of a predominantly Christian rebel group in the Central African Republic for multiple war crimes committed against Muslim civilians during the country’s civil war in 2013 and 2014, sentencing each to more than a decade in prison.

The former president of the CAR Football Federation, Patrice-Edouard Ngaissona, along with Alfred Yekatom, a rebel leader known as “Rambo,” were found guilty on Thursday of their involvement in atrocities including murder, torture and attacking civilians.

The court sentenced Yekatom to 15 years for 20 war crimes and crimes against humanity.

Ngaissona received 12 years for 28 counts of war crimes and crimes against humanity.
