Billions of locusts swarming through East Africa are the result of extreme weather swings and could prove catastrophic for a region still reeling from drought and deadly floods, experts said Friday.

Dense clouds of the ravenous insects have spread from Ethiopia and Somalia into Kenya, in the region's worse infestation in decades.
The UN's Food and Agriculture Organization (FAO) estimated one swarm in Kenya at around 2,400 square kilometres (about 930 square miles) -- an area almost the size of
Moscow -- meaning it could contain up to 200 billion locusts, each of which consume their own weight in food every day.
