In a Lithuanian forest, an international research team has pinpointed the location of a legendary tunnel that Jewish prisoners secretly dug out with spoons to try to escape their Nazi captors during World War II, the Israel Antiquities Authority announced on Wednesday.

The tunnel, located in the Ponar forest, known today as Paneriai, outside of the Lithuanian capital of Vilnius, is the site where some 100,000 people, including 70,000 Jews, were killed and thrown into pits during Nazi occupation.

In the quest to find the tunnel, the team of archaeologists, geophysicists and Jewish historians from Israel, the United States, Canada and Lithuania did not want to disturb any human remains in the mass burial pits at the site.
