Angola is now denying the report:

The Angolan embassy in Zimbabwe rejected Thursday as "completely false" reports that the Angolan government would send 3,000 policemen to Zimbabwe to bolster the security forces there.

"This information is completely false," it said in a statement.

"It is not the custom of the Angolan government to interfere into the internal matters of other governments," the embassy said in Harare, adding the Zimbabwean forces were "capable enough to solve any internal issues."
