Mugabe turns up heat on Tsvangirai

Just three weeks before the runoff election, Zimbabwe’s president Robert Mugabe is giving the opposition no room to manoeuvre – harassing and threatening to arrest its candidate, banning its rallies and attacking diplomats who try to investigate political violence.

Even food is a weapon, with a ban on aid agencies ensuring the poorest Zimbabweans must turn to Mr Mugabe for help even if they blame him for the collapse of the economy.
