Speaking from an official visit to Nairobi The United States Secretary of State John Kerry added his voice to calls for the president not to take part in the June election.
He said it is against the constitution.
The Vice President of the constitutional court which was due to decide if Nkurunziza’s bid is legal has fled the country.
He said he refused to be pressured to put his name to it.
Regional and European governments have also made the plea saying his candidacy risks undermining the Arusha peace deal which ended the ethnically fuelled civil war a decade ago.
