Trucks of soldiers and police entered the Central Kalahari Game Reserve last week, according to Survival International. Survival believes this is to intimidate the Bushmen, and perhaps even force them out, because:
1) Gem Diamonds wants to open a diamond mine on their land (Gem Diamonds is based in London);
2) the Botswana High Court is now due to hear a Bushman application to reinstate their water borehole.
