A tunnel that was dug by Jews to escape Nazi death squads has been unearthed in Lithuania, according to a team of archaeologists from the United States, Israel and Canada.
The tunnel was dug in 1944 by prisoners being held in a pit at the Ponary killing fields outside Vilnius, Lithuania.
They were brought over from the Stutthof concentration camp, in what is now Poland, for the purpose of digging up the mass graves at Ponary, where an estimated 100,000 people had been killed there since 1941.
They were ordered to take the bodies - most of them Jews ripped from Vilnius and other Jewish enclaves - and stack them into pyres and burn them, in an effort by the Nazis to hide the atrocity from the advancing Soviet forces. For this, they were known as the "Burning Brigade".
At night the Nazis kept the prisoners in pits, and that's when a group of about 80 decided to take matters into their own hands. Using their bare hands, spoons and anything else that could be used as a tool, they spent three months making a tunnel.
