President Barack Obama is on his way back to the US after visiting Tanzania, the last leg of his Africa tour, which also included Senegal and South Africa.
Earlier he laid a wreath for the victims of the 1998 US embassy bombing in the Tanzanian city of Dar es Salaam.
The president was joined for the ceremony by predecessor George W Bush.
During his stay, he also visited a US-owned power plant, following his announcement over the weekend of a multi-billion-dollar electricity initiative.
