Doctors Without Borders says one of its health workers has been killed by an armed group in Central African Republic.

The organization says assistant nurse Gaulbert Mokafe was killed on Thursday between Batangafo and Bouca while traveling by motorcycle to visit family.

The medical charity demands that armed groups control their members and ensure the protection of civilians and health workers. Doctors Without Borders says it has more than 200 international staff and more than 2,000 local staff working in the country.

The government and 14 rebel groups signed a fragile peace agreement in February that many hoped would be a turning point in the nation that has seen deadly communal violence since 2013.
