Pope Francis' first Africa trip will highlight the problem of a lack of dialogue between Christianity and Islam, the two fastest growing religions on the continent.
On his first full day in Kenya, Francis insisted on Thursday that religion could never be used to justify violence and lamented that "all too often young people are being radicalised in the name of religion to sow discord and fear, and to tear at the very fabric of our societies".
He said interfaith dialogue is not a luxury or optional, but is simply "essential".
The 78-year-old will use his 11th overseas trip since taking office in 2013 to deliver a total of 19 speeches on peace, social justice, environmental protection, and interfaith dialogue.
In addition to Kenya, the pope is visiting Uganda and the Central African Republic during his six-day African tour.
