"Any future requests to be excused from attending parts of his trial will be considered on a case-by-case basis," The Hague-based ICC said in a statement.
Kenyatta's trial on charges of masterminding some of the 2007-8 post-election violence in Kenya that left over 1,000 people dead and several hundred thousand displaced, is set to start on February 5.

Both men have pledged full cooperation with the court.
