In Pictures: African countries battle locust invasion
One swarm measured 60km (37 miles) long by 40km (25 miles) wide in Kenya’s north east, according to the Intergovernmental Authority on Development.
Locusts by the millions are chomping their way across a large part of Africa in the worst outbreak some places have seen in 70 years.
The locusts are threatening some of the world’s most vulnerable countries, where millions of people already live with the periodic risk of drought or flooding.
“A typical desert locust swarm can contain up to 150 million locusts per square kilometre,” East African regional body the Intergovernmental Authority on Development (IGAD) has said.
