Locust plague: Millions at risk of famine

The threat of a billion locusts sweeping across East Africa and South Asia feeding on farms and fields prompts urgent warnings.

It is the worst invasion of desert locusts in a quarter of a century.

The food supplies and livelihoods of millions across East Africa and South Asia are under threat.

The situation has been declared a national emergency in some countries, including Somalia and Pakistan.
