This is the first I have heard of the MDC. It is a good article ... sounds Mugabe wants to hold onto power. Not just drive out whites.
Get a shortwave radio. Radio Canada, the BBC, VOA/Africa, and even Radio Nederland have had updates on Zimbabwe. The BBC reporter got kicked out during the last "election".
Not sure what you can pick up in Kali, but on the East Coast, a lot of countries broadcast out of the Caribbean, though not
directed to the North America, or to NA out of New Brunswick, CA.
VOA? Sometimes out of North Carolina, but reception may be better from Botswana.
For general broadcast schedules, ilgradio.com publishes a quarterly, but slightly behind (it's free) schedule of
broadcast times/frequencies. Poke around for free software, and there are a couple of programs that will sort the
records, for say, english, on-air-now.
