The International Criminal Court has given prosecutors an ultimatum of one week to provide the court with evidence against Kenya's President Uhuru Kenyatta, or drop the charges.
The court, based in The Hague, ruled that further delays would be "contrary to the interests of justice".
Rejecting the request for a delay, the judges said the prosecutors needed to decide within a week whether it would withdraw charges or that the "evidentiary basis has improved to a degree which would justify proceeding to trial".
Kenyatta, became the first serving head of state to appear before the ICC in October, however prosecutors asked to delay the case as they were attempting to gather further evidence.
ICC Chief Prosecutor Fatou Bensouda accused the Kenyan government of withholding evidence, including items such as Kenyatta's bank statement. At least seven witnesses have also dropped out amidst allegations of bribery and intimidation.
Kenyatta is accused of crimes against humanity, over his alleged role in election violence that left 1,200 people dead in 2007.
