Protesters in Haiti attacked United Nations forces yesterday, accusing them of causing the country’s cholera outbreak.
The violence erupted in the northern cities of Cap-Haitien and Hinche where Angry demonstrators blocked roads, threw rocks and shouted anti-UN slogans. One civilian was shot, six peacekeepers injured, Reuters notes.

And, while the source of the outbreak may remain a mystery, the threat to Haiti is all too clear: Political violence threatens to destabilize the island heading into the country’s presidential and legislative elections on November 28.
