President Obama’s Air Force One touched down at Nairobi’s international airport. Arriving in the country where his father was born, he was greeted at the airport by President Kenyatta with a handshake and embrace. According to BBC Mr Obama also hugged his half-sister Auma, who then travelled in the presidential limousine to the hotel where the US leader is staying. Crowds cheered the motorcade along its route. At dinner, the president was joined by more relatives, including the woman known as “Granny” or “Mama Sarah”, who helped raise his now-deceased father. Security is tight. The Kenyan capital is in lockdown, many streets are closed and people are opting to stay at home. Mr Obama, the first sitting US president to visit Kenya, will hold talks on trade and investment, and also security and counter-terrorism.
