According to a list published in a book (Zanzibar Dola, Taifa na Nchi Huru) by Dr. Yussuf S. Salim of the Zanzibar Center of Human and Democratic Rights based in Denmark, those not seen in this picture are Yusuf Himid and Khamis Hemedi. Based on our recollection, Yusuf Himid became the first leader of the Nyuki Brigade, the Zanzibar's division of the Tanzania People's Defence Forces (TPDF). Upon his death in early 80's, Khamis Hemedi succeeded him in the same capacity.
