Port-au-Prince: Fresh rioting broke out in Haiti with one new fatality in a clash with UN peacekeepers blamed by some for the cholera outbreak, as fears grew that the epidemic may spread beyond Haiti`s borders.
A man was shot dead and several others injured in northern Haiti, the first area of the outbreak which officials said could kill as many as 10,000 people.
Haiti`s Health Ministry said on Wednesday that 1,100 people have now died from cholera since the disease was first detected in late October. The number of people hospitalised also grew to 18,382.
"Our projections show that we could have around 200,000 cases of infection in Haiti over the next six to 12 months," Pan-American Health Organisation regional advisor Ciro Ugarte said.
"If the fatality rate (of four to five percent) is maintained... we may have 10,000 dead," said Ugarte.
Isolated cholera cases have been found in the Dominican Republic -- it shares the Caribbean island of Hispaniola with Haiti -- and as far away as the southern US state of Florida.
Aid workers complained that protests were holding up relief operations in the second city of Cap Haitien, while a top UN official said the demonstrations were being "orchestrated”.
Two Haitians were killed in riots in Cap Haitien on Monday, one shot by a UN peacekeeper as protesters set a police station and vehicles ablaze and threatened to torch a UN compound.
A police source said a third person was shot dead in fresh rioting in the city on Wednesday. It wasn`t clear if the latest fatality was a UN peacekeeper, a member of the Haitian police, or a protester.
UN spokesman Vincenzo Pugliese could not confirm the fatality, but said UN workers had not been able to get to work on Wednesday because of the tensions in the city.
The Oxfam aid group confirmed the protests and said it was worried that the unrest could lead to a faster spread of the cholera that has already killed more than 1,100 people in the country.
The UN said that in one incident this week, a World Food Programme (WFP) warehouse had been looted of 500 tonnes of food and burned.
