KAUNAS, Lithuania — Pope Francis on Sunday warned against revisionism and any rebirth of the anti-Semitism that fueled the Holocaust, as he marked the annual remembrance for Lithuania’s centuries-old Jewish community that was nearly wiped out during World War II.

Francis began his second day in the Baltics in Lithuania’s second city, Kaunas, where an estimated 3,000 Jews survived out of 37,000 during the 1941-44 Nazi occupation. He ended it back in the capital, Vilnius, to pay his respects to Lithuanians who were deported to Siberian gulags or were tortured, killed and oppressed at home during five decades of Soviet occupation.

Francis also honored freedom fighters at the former KGB headquarters where anti-Soviet partisans were detained and executed, solemnly touring the chambers that have now been turned into a haunting museum of the occupation.

Francis also recalled that Sunday was the 75th anniversary of the destruction of the ghetto in Vilnius, which had been known for centuries as the “Jerusalem of the North” for its importance to Jewish thought and politics. Each year, the Sept. 23 anniversary is commemorated with readings of the names of Jews who were killed by Nazis or Lithuanian partisans or were deported to concentration camps.
