Cyclone Gamane hit northern Madagascar on Wednesday and has now weakened considerably, leaving a trail of destruction behind it.
Madagascar has been hit by at least 10 strong tropical cyclones since the start of 2022 and is facing a hunger crisis in parts of the island, due to the damaging impact of extreme weather, according to the World Food Program.
The United Nations said the number of cyclones in the past two years is unprecedented for Madagascar, which has also suffered from its worst drought in 40 years in the south. It is one of the countries most at risk to climate change and one with the highest rates of poverty, according to the World Bank.
