President Sergio Mattarella marked Liberation Day by laying a wreath on the tomb of the unknown soldier in Rome.
The anniversary marks the day in 1945 when the Italian resistance movement proclaimed an insurgency as the Allies were pushing German forces out of the peninsula.

"After the capture of Rome, it took a long time to get the Germans out of there. They were fighting bitterly to keep us occupied, to keep the troops there so they didn't go over onto the Western front," said Bria.
German forces surrendered in Italy just over a week before signing a total and unconditional surrender to Allied Forces in Europe on May 7, 1945.
