Cyclone Idai and the mounting death toll is “yet another alarm bell about the dangers of climate change” UN Secretary-General António Guterres said on Tuesday, warning that vulnerable countries like Mozambique, would be hit the hardest unless urgent action is taken by nations across the world.

A week after the flooded Mozambican port of Beira was hit by Cyclone Idai, “aid agencies are barely beginning to see the scale of the damage”, the head of UNICEF said on Saturday, as she called for more international support to help quickly get relief to more than a million people across the country and prevent the possible spread of waterborne diseases like cholera.

The world needs to step up support for the survivors of Tropical Cyclone Idai, the UN Secretary-General said on Friday, in a strong personal appeal as relief workers rush to provide aid to people stranded across the storm countries in southern Africa.

As the full scale of the devastation caused by Cyclone Idai in southern Africa continues to be assessed, the UN and humanitarian partners are ramping up the provision of emergency food, shelter, water and health care supplies to hundreds-of-thousands who have been affected across Mozambique, Malawi and Zimbabwe.
