At overflowing garbage dumps in Zimbabwe’s capital, desperate vagrants pounced on trash bags and fought over chicken bones and scraps of discarded food. Sewage clogged streets and most shopkeepers didn’t even bother with holiday decorations.

Nobel Peace Prize winner Desmond Tutu said Wednesday that the international community must use the threat of force to oust Zimbabwe’s Robert Mugabe from office.

The United States can no longer support a proposed Zimbabwean power-sharing deal that would leave Robert Mugabe, “a man who’s lost it,” as president, the top American envoy for Africa said Sunday.

President Robert Mugabe claims the cholera crisis that has killed nearly 800 people in Zimbabwe is contained, and his spokesman said his much-criticized remark that there was no cholera was misunderstood, state media reported Friday.

Because of the growing humanitarian crisis in Zimbabwe, which has been spurred by a lack of water and the rapid spread of deadly cholera, Robert Mugabe is facing increased pressure to step down as President.

Secretary of State Condoleezza Rice said Friday that it is “well past time” for Zimbabwe’s President Robert Mugabe to leave office as evidenced by the nation’s calamitous cholera epidemic and health care crisis.

Zimbabwe has declared a national emergency over a cholera epidemic and health care system collapse, and is seeking more international help to pay for food, drugs and hospital equipment, the state-run newspaper said Thursday.

Former U.S. President Jimmy Carter said Monday the crisis in Zimbabwe appears “much worse than anything we ever imagined” after the government there blocked his weekend humanitarian visit.

Zimbabwe’s opposition party said Thursday that four of its activists were killed in a firebombing near Harare amid growing concerns that President Robert Mugabe will use a violent crackdown to steal an upcoming runoff election.
