Pope Francis begins four-day visit to Baltics amid Russia's rising tension

Russia will be the elephant in the room as Pope Francis begins a four-day visit to the Baltics amid renewed alarm about Moscow's intentions in the region it has twice occupied.

Francis is traveling to Lithuania, Latvia, and Estonia to mark the 100th anniversaries of their independence and to encourage the faithful in the nations, which saw five decades of Soviet-imposed religious repression and state-sponsored atheism.

"Fifty years of occupation left their mark both on the church and on the people," said Monsignor Gintaras Grusas, archbishop of Vilnius. "People have deep wounds from that period that take time to heal."

Francis lands Saturday in the Lithuanian capital Vilnius to begin four-day, three-country trip that will feature encounters with political leaders as well as the Catholic, Lutheran and Russian Orthodox faithful.
