Pope Francis embarks on 11-day Asia-Pacific tour, his longest trip yet

Pope Francis is set to embark on his longest trip since becoming head of the Catholic church in 2013. The 87-year-old leaves Rome tonight and will visit four Asia-Pacific countries -- Indonesia, Papua New Guinea, Timor-Leste and Singapore -- over the next 11 days. One key theme of this trip is inter-religious harmony. Pope Francis is set to engage not only with local Catholic groups, but also leaders of other religions and political figures.
