- Swarms have already devastated farmland in Kenya, Somalia and Ethiopia
- They are now threatening to spread to South Sudan, Uganda and Eritrea
- Tens of thousands of acres of crops destroyed putting food supplies at risk
Swarms of desert locusts could ravage more countries in eastern Africa and threaten the livelihood of many more people, the United Nations' Food and Agricultural Organization said on Monday.
The swarms, first sighted in December, have already destroyed tens of thousands of hectares of farmland in Kenya, Somalia and Ethiopia, threatening food supplies in many areas.
In Kenya, it's the worst locust invasion in 70 years.
The swarms are now threatening to spread to South Sudan, Uganda and Eritrea, said Bukar Tijani, assistant director-general of the FAO's agriculture and consumer protection department.
