The International Criminal Court has said that two witnesses have withdrawn from testifying at President Uhuru Kenyatta’s case over security concerns.
ICC spokesperson Fadi El Abdallah told the BBC: "The prosecutor might seek to add other witnesses in the future if suitable replacements for these witnesses are forthcoming."
Kenyatta has been charged over election violence in 2007 which left over 1,000 people dead.
The ICC has previously accused Kenya of not doing enough to protect witnesses.
