Others are Afaan Oromo and Amharic, spoken in Ethiopia; Tigrinya, the main language of Eritrea; Gujarati, Marathi and Telugu and Punjabi.
According to BBC Director General, Tony Hall, the move is historical and reinforces the importance of the organisation globally.
“This is a historic day for the BBC, as we announce the biggest expansion of the World Service since the 1940s. The BBC World Service is a jewel in the crown – for BBC and for Britain,” he said.
Director of the World Service, Fran Unsworth, said, “Where the money comes from is irrelevant. The World Service is going to do what it’s always done – go over the heads of government providing a service directly to citizens of the world.”
