VATICAN CITY (AP) " Pope Francis's weekend trip to Morocco aims to highlight the North African nation's tradition of Christian-Muslim ties while also letting him show solidarity with migrants at Europe's door and tend to a tiny Catholic flock on the peripheries.

Francis will address the first two items on the agenda Saturday when he begins his 27-hour visit to Rabat, the Moroccan capital. He'll tend to the third when he wraps up the visit with a Mass and a meeting with Moroccan clergy on Sunday.

The highlight of the trip is likely to be Francis' visit Saturday to the Mohammed VI Institute, a school of learning for imams that epitomizes Morocco's efforts to promote a moderate brand of Islam and export it via preachers to Africa, the Middle East and Europe.
