This comes as a Zimbabwean human rights group accuses the government of using violence in rural areas to rig a possible presidential run-off. A BBC contributor in the southern town of Masvingo reports that the bodies of two opposition activists have been found after they were abducted.
Allies of President Robert Mugabe say the violence is being exaggerated. Another BBC contributor, in the eastern town of Mutare, reports that opposition activists are starting to take revenge on ruling party militants. He says they burnt down a militant base in Odzi, just north of Mutare on Monday, while the state-owned Herald newspaper says an army training camp was attacked.
He has to back somehow, now Mugabe has the whole international community against him, even his last allies leaving him!
