ROME (AP) — Previously unpublished World War I images and documents are on display at Italy’s Tomb of the Unknown Soldier starting Saturday, commemorating the 100th anniversary of the bloody conflict that many historians say united Italians in common cause for the first time.

The exhibit features images of executions and emaciated prisoners of war that were censored during wartime, as well as notifications for military tribunal death sentences that were posted on the streets of Rome.
