US President Donald Trump has tweeted that his wife Melania Trump "is doing really well in Africa".

"The people love her, and she loves them! It is a beautiful thing to see," he tweeted.

Mrs Trump flew into Kenya on Thursday evening, after visits to Malawi and Ghana.

An entire terminal at Kenya's main international airport in Nairobi was closed for her arrival, and the same will happen when she flies out to Egypt, the final stop of her solo African tour, the BBC's Ferdinand Omondi reports from the capital.

While in Kenya she will see some of the country's wildlife, and watch a performance at the National Theatre.

Mrs Trump has also said she is looking forward to meeting her Kenyan counterpart. She has commended Margaret Kenyatta’s "Beyond Zero" campaign, which promotes healthcare for mothers and their babies.

Mrs Trump is promoting her "Be Best" campaign, which seeks to improve the lives of children. But so far she has received a lukewarm reception on the continent, our correspondent says.
