Two fatal landslides in the earthquake affected areas of Haiti

Problems continue in the earthquake affected areas of Haiti, where over 2 million people remain essentially homeless 10 months after the devastating earthquake.  Reporters Live are carrying a story that heavy rainfall in the last 48 hours has triggered two, rather different fatality-inducing landslides: 1.

The translation says: “The dam is large and there are still several tens of metres before the water passes over it. The problem is that it has hardly rained since the earthquake of January 12.
