Pope Francis celebrates rain-soaked Mass in Kenya
Crowds line up to celebrate Mass with Pope Fran
Tens of thousands of people have been celebrating Mass with Pope Francis at a university campus in Kenya.
Pope Francis made a plea for traditional values, saying "the health of any society depends on the health of its families".
The Pope earlier urged Kenyans to work for peace and reconciliation on his first trip as pontiff to Africa, amid a rise in militant violence.
He arrived in Kenya on Wednesday, the first stop on a three-nation tour.
President Uhuru Kenyatta and ululating crowds had welcomed him at the airport in Nairobi, the capital.
