The International Criminal Court has begun a preliminary investigation into allegations of crimes against humanity in Ukraine leading up to the fall of ousted president Viktor Yanukovich.
The ICC said on Twitter:
The International Criminal Court has acquitted the Congolese warlord Ngudjolo Chui of all charges of war crimes and crimes against humanity.
Ngudjolo had been accused by prosecutors of directing militias to kill, pillage and rape during a conflict in the northeastern Ituri province of Congo in 2003.
Presiding judge Bruno Cotte said atrocities had been committed during the conflict but prosecutors had failed to tie them to Ngudjolo.
Congolese rebel leader Thomas Lubanga has been found guilty of recruiting and using child soldiers during the Democratic Republic of Congo's 1998 to 2003 war.
The verdict was the first delivered since the International Criminal Court in the Netherlands was formed.
