Pope Francis has called for an investigation to determine if Israel's attacks in Gaza constitute genocide, according to excerpts released from an upcoming new book. It's the first time Francis has openly urged for an investigation of genocide allegations over Israel's actions in the Gaza Strip. The book, entitled 'Hope never disappoints. Pilgrims towards a better world,' will be released on Tuesday ahead of the pope's 2025 jubilee. In the book, Francis also speaks about migration and the problem of integrating migrants in their host countries.
