Ethiopian runner Feyisa Lilesa, famous for his protest at the Rio Olympics in 2016, has spoken to the BBC after returning home from self-imposed exile in the US.

The marathon runner first hit the headlines when he crossed the line in second place at Rio with his arms above his head in solidarity with protesters from Ethiopia's ethnic Oromo population, who were suffering a brutal crackdown from the government.

"While I was in exile I thought of my people's struggle day and night," he told the BBC.

The silver medallist's return has been made possible following the appointment of new Prime Minister Abiy Ahmed. Mr Ahmed, the country's first Oromo head of state, has brought in sweeping reforms since coming to power in April.
