Ethiopia's Prime Minister Abiy Ahmed has called on the authorities in regional states to address the ethnic tensions that have led to tens of thousands of people being displaced by violence.

Mr Abiy also defended the radical reforms he has undertaken - they include opening up the political space and making peace with long time enemy Eritrea.

He was addressing a conference of the ruling EPRDF coalition - his first speech to the gathering as prime minister.

Mr Abiy's chief of staff has been tweeting extracts from his speech in which he called for unity.
