The International Criminal Court will rule on Tuesday on an appeal by the Democratic Republic of Congo's rebel leader, Bosco Ntaganda, against his conviction for war crimes.

The former commander, nicknamed "The Terminator", was given a 30-year jail sentence in 2019 after being found guilty on 18 counts including murder, rape and using child soldiers.

He was the first person to be convicted by the court of sexual slavery.

The charges related to crimes carried out in the mineral-rich Ituri region of the Democratic Republic of Congo in 2002 and 2003.

Prosecutors are asking the judges to consider a tougher sentence.
