US President Barack Obama lands in Ethiopia

US President Barack Obama landed in Ethiopia on Sunday, beginning a two-day stay and becoming the first American leader to visit Africa's second most populous nation.

Air Force One touched down at Addis Ababa's international airport after a short flight north from the Kenyan capital Nairobi.

The visit will include talks with the Ethiopian government, a key strategic ally but criticised for its record on democracy and human rights.

Obama will also become the first US president to address the African Union and hold talks with regional leaders on the civil war in South Sudan.
