Fighting in southern Ethiopia has pushed some 50,000 people across the border into Kenya since clashes erupted last week, the United Nations said, citing local authorities.

Fatima Mohammed-Cole, the United Nations High Commissioner for Refugees (UNHCR) representative for Kenya, said up to 50,000 people have crossed into Kenya, according to local authorities. The clashes pit the armies of the Somali and Oromia regions against each other.
