Political tension in Haiti threatens to severely hamper the country's fight against a cholera outbreak that has already killed thousands since October.

The country has been in a state of turmoil since a November 28 presidential election was marred by widespread allegations of fraud.  

Meanwhile, the UN secretary general has appealed for more international aid to combat the cholera outbreak, saying the disease could affect more than 600,000 Haitians over the next six months.
