Pope Francis has doubled down on his traditional views on abortion and women during his in-flight news conference coming home from Belgium.

Pope Francis implored bishops not to cover up the sexual abuse of children, during an open-air mass on Sunday that capped a three-day visit to Belgium, which is still struggling with the legacy of past scandals.

The pope also had a number of off-program appointments during the visit — he surprised elderly at a care home, crashed a Catholic youth encounter, and prayed in front of the tomb of Belgian King Baudouin, a Catholic who temporarily abdicated the throne rather than sign a law legalizing abortion in 1990.
