President Obama visits Tanzania – Nima Elbaghir reports

President Obama spent an emotional weekend in South Africa, where former South African President Nelson Mandela is still in critical but stable condition at a hospital in Pretoria.

Mandela is said to be still on life support, with his family by his bedside.

While he did not see Mandela himself, the president did meet with Mandela's family. He also visited Robben island where the anti-apartheid icon was held prisoner for many years.

The president is now on his way to Africa's east coast, to visit Tanzania.
