The witnesses said officers in downtown Harare ran into a march of doctors and nurses - some in uniform - who fled the police charge. A few blocks away, police stopped teachers trying to join the same protest. At least six people were taken away in police trucks, according to the witnesses who declined to give their names for fear of official retribution.
The unions are joining a mass movement to press the government to respond to the worsening crises. Men in the blue uniforms of paramilitary police armed with rifles were seen positioned atop several high-rise bank headquarters.
On Monday, soldiers went on a rampage after they were unable to withdraw wages from banks. The banks have been short of cash as a result of Zimbabwe's economic meltdown. Zimbabwe's state newspaper quoted defence minister Sydney Sekeramayi as saying that rogue elements in the country were trying to incite violence against the government.
UN says 565 dead so far
He said the coincidence of Monday's incident and the call for protests by unions and civil rights organisations "raises a lot of questions" and that any unlawful demonstrations would not be tolerated. Zimbabwe Congress of Trade Unions Secretary-General Wellington
Chibebe told The Associated Press that he and at least seven other labour leaders were picked up by security forces and released after several hours on Wednesday.
He said they were asked to with police and the central bank governor on Thursday. The United Nations said that deaths from the cholera epidemic had risen to 565, with 12 546 people infected. The government had been reporting 473 cholera deaths since August, and a total of 11 700 people infected as of Monday.
The nationwide outbreak of the waterborne disease is blamed on collapsing water treatment plants and broken sewage pipes.
The country is suffering from the world's highest inflation and Zimbabweans face daily shortages of food and other basic goods. Many hospitals and clinics have been forced to shut their doors because of a lack of drugs and medicines.
Water restored to Harare
On Wednesday, water supplies were restored to parts of Harare after authorities turned off the taps for three days. They said they had run out of purifying chemicals. Zimbabwe's government is cooperating with aid agencies to try to stem the spread of cholera but has stopped short of declaring the epidemic a national emergency.
The European Commission said it was providing more than $12 million for drugs and clean water while the International Red Cross was also releasing more funds to deal with the epidemic.
"Cholera is a disease of destitution that used to be almost unknown in Zimbabwe," Louis Michel, the European Commissioner for Development and Humanitarian Aid said.
The Herald newspaper also reported that Zimbabwe's Reserve Bank has unveiled a new ZW$100 million note to go into circulation on Thursday. The paper said that the ZW$10 million, ZW$50 million and ZW$100 million notes are aimed at easing access to cash, although they are unlikely to end long lines at banks.
Thursday will also see an increase in the amount of cash an individual can withdraw to ZW$100 million a week. At the dominant black market exchange this is equivalent to $40, which buys about 50 loaves of bread or in some cases only 40 litres of water. – (Sapa, December 2008)
