Nine people have died from a cholera outbreak in Ethiopia's north-western Benishangul-Gumuz Region, state television (ETV) reported on Sunday, citing health authorities.

A regional health official, Abdulmunhem Al-Beshir, said that "some 131 people have been infected in the outbreak while nine others died," ETV said.

Cases have been reported in three districts, according to the Benishangul-Gumuz Health Bureau.

Meanwhile, a cholera outbreak also killed nine Sudanese refugees in Ethiopia's north-western Amhara region.

Local media say the cholera outbreak has spread through 11 regions of Ethiopia in the past year, killing 320 people.

A two-year civil war and a drought have caused a severe humanitarian crisis in the region.
