A Zimbabwe state-run newspaper says four people have appeared in court for facing charges of booing the country's first lady, who has moved closer to succeeding her husband as president.
The Zimbabwe Herald reports that three men and a woman from Bulawayo are accused of booing Grace Mugabe at a ruling party rally last weekend attended by President Robert Mugabe.
The report says they face charges of undermining the authority of the president.
State prosecutor Jerry Mutsindikwa says the four allegedly sang "We hate what you're doing" as the first lady spoke.
The 93-year-old president last Monday fired his deputy and longtime ally Emmerson Mnangagwa, accusing him of plotting to take power via witchcraft. Grace Mugabe is expected to replace Mnangagwa as one of Zimbabwe's two vice presidents next month.
