Pope Francis is due in Kenya at the start of a three-nation African tour – his first to the continent as pontiff, the BBC reports.
Thousands are expected to line the streets of the capital, Nairobi, to welcome him for his three-day stay.
An atheist group says it will challenge in court a government decision to declare Thursday a holiday in honour of the pontiff, local media reports.
He is also due to visit Uganda and Central African Republic, which has been hit by Christian-Muslim conflict.
