The International Criminal Court has unsealed an arrest warrant for two Kenyans suspected of bribing prosecution witnesses in return for withdrawing from cases or recanting their testimony.

The court unsealed the warrant for Paul Gicheru and Philip Kipkoech Bett on Thursday, saying the suspects were arrested in July by Kenyan police.

Prosecutors' cases in Kenya, which focus on postelection violence in 2007-08 that left more than 1,000 people dead, have been beset by claims of witness interference.

In March, the court dropped a case against Kenyan President Uhuru Kenyatta for lack of evidence. Prosecutors had alleged that Kenyatta helped organize violence in the aftermath of his country's 2007 election — a charge he denied.

Court spokesman Fadi El Abdallah says it is not clear where Gicheru and Bett are now.
