Arabic Speaking Africans
Spanish West Africa, Morocco, Tunisia, Algeria, Libya, Egypt, Zanzibar etc.
 

Please Note: As I do not read Arabic, it has been impossible for me to decipher the script on those images of Arabic flags I have seen. The script on these flags was generated using an Arabic font and is meaningless (and hopefuly not insulting). The flags are copied from some line drawings I have and from flags seen in movies - notably, the Wind and the Lion and Lion of the Desert. They are therefore to be considered highly speculative but plausible.
