Zimbabwe's Mugabe Must Stand Down

HARARE (Reuters) - Zimbabwean President Robert Mugabe has until noon (5.00 a.m. EST) on Monday to stand down or the ruling ZANU-PF will begin impeachment proceedings after the 93-year-old leader defied expectations he would resign. Mugabe stunned Zimbabweans in a rambling late night Sunday television address by avoiding any mention of resignation, pledging instead to preside over a congress next month of ZANU-PF, which had sacked him as its leader only hours earlier.
