Pope Francis has urged Kenyans to work for peace and reconciliation as a rise in militant violence threatens his first trip as pontiff to Africa.
He arrived in Kenya on Wednesday, at the start of a three-nation tour of Africa.
President Uhuru Kenyatta and ululating crowds welcomed him at the airport in the capital, Nairobi.
The Pope said conflict and terrorism fed “on fear, mistrust, and the despair born of poverty and frustration”.
The pontiff played down security fears about his trip, joking that he was “more worried about the mosquitoes.”
An atheist group said it would challenge in court a government decision to declare Thursday a holiday in honour of the pontiff.
Pope Francis’s five-day visit will also see him go to Uganda and Central African Republic, which has been hit by Christian-Muslim conflict.
