A former UN secretary general, Kofi Annan has accused the International Criminal Court (ICC) of mishandling the cases against Kenya’s leaders.
Mr Annan said President Uhuru Kenyatta and his deputy William Ruto should not have remained free during their trials.
Crimes against humanity
The ICC dropped charges of crimes against humanity against both men but said witnesses had been intimidated.
The cases are related to violence after disputed elections in 2007.
About 1,500 people were killed and 600, 00 forced from their homes as ethnic clashes spread around the country.
Both men denied the charges and accused the ICC of unfairly targeting African leaders.
Kenya says it will withdraw from the ICC.
