Kenya's president is seeking to halt his International Criminal Court trial before it starts, claiming that corrupt witnesses and intermediaries for the prosecution make a fair trial impossible.

In a written request filed Thursday, Uhuru Kenyatta asks the court to permanently end the case against him because "the prosecution is presiding over an utterly corrupt and dishonest case."

He is due to go on trial Nov. 12 for crimes against humanity allegedly committed during violence that raged after Kenya's disputed 2007 presidential elections.

Kenyatta, who was elected president at elections earlier this year, denies the charge, and his lawyers have repeatedly claimed that the prosecution case against him is based on false testimony.

Prosecutors are expected to respond in writing, and the court could order a hearing into the claims.
