Tanzania: President Obama arrives in Dar es Salaam
US President Barack Obama has said he wants a "new model" for development during his first visit to Tanzania.
Mr Obama and his family were greeted by Tanzanian President Jakaya Kikwete and troupes of dancers as they arrived in the main city of Dar es Salaam.
In a speech on the last leg of his Africa tour, the US president said Tanzania had the potential to transform the region.
Trade is expected to top the agenda as he holds talks with business leaders.
The BBC's Salim Kikeke reports from Dar es Salaam, where he also interviewed Ngasuma Kanyeka, a youth worker who says Tanzanians must capitalise on the opportunities that President Obama's visit represents.
