Sangala is a fictional African nation appearing in season 7 of the US TV series "24." The name may be a combination of Senegal and Angola.

From <http://24.wikia.com/wiki/Sangala>:

Sangala observes Greenwich Mean Time; it is probably located in West Africa, directly south of the United Kingdom. Judging by comments from the presidential staff about launching their attack from the sea, it can be presumed that it is a coastal country. The majority of filming scenes for Sangala took place around Cape Town, South Africa. The official languages of Sangala seem to be English and French.

The Sangalan flag is shown during the White House hostage crisis: - I am going from memory, but it was horizontally striped yellow-green-red-white-red-green-yellow, 1:1:2:2:2:1:1 or so, with a brown charge in the center consisting of two brown dogs or lions sejant with intertwined tails.
