This week there have reports, including the BBC, that Angola was sending 2500 para-military police, known as the Ninjas, to Zimbabwe as fraternal assistance.

Now the Angolans have issued a denial:

The Angolan government has issued a categorical denial of this story.
It's being suggested that the source of the story was a recent arrangement
for Angola to train Zimbabwe police. Itself an interesting story. Both Reuters and the BBC carried stories about the denial:

There is also a report of the Zimbabwean Vice-President having a secret meeting in Johannesburg with her South African opposite number; the Vice President's husband is a former Zimbabwe Defence Force commander.

Murky business.
