Kindergarten and nursery in Burundi? (Bujumbura)

Hello! We are moving to Bujumbura in September and I am looking in to schools for my 3-year old son. I found the contact information for the French and Belgian school but cannot seem to find anything on English-speaking schools. There seems to be at least one international school. Would somebody have more information about English speaking kindergartens and if possible some contact details?
Also, if someone knows about a good nursery (preferably English speaking but French speaking is good as well) I could need it as well for my 1.5 year old daughter.
Thank you very much for your help and I look forward to hearing back from you!
Leonie
