Plague of locusts in Madagascar
A severe plague of locusts has infested about half of Madagascar, threatening crops and raising concerns about food shortages, a UN agency says.
The UN's Food and Agricultural Organization (FAO) said billions of the plant-devouring insects could cause hunger for 60% of the population.
About $22m (£14.5m) was urgently needed to fight the plague in a country where many people are poor, the FAO added.
