Lithuania: Holocaust escape tunnel discovered in Ponar forest

A 30-metre (100-foot)-long escape tunnel, dug by Jewish prisoners in the 1940s to flee the infamous Ponar Nazi camp, was uncovered near Vilnius, Friday.
Some 100,00 people were massacred and thrown into pits in the Ponar forest by the Nazis. In 1943, the camp set up a special unit known as the 'Burning Brigade' who forced prisoners to dig mass graves and burn corpses to cover up the mass genocide.
According to witness accounts, including that of survivor Mordechai Zeidel, prisoners began to dig a tunnel, and 40 prisoners made their escape on the 15 April 1944. Many of the escapees were however shot down by Nazi troops and only 11 survived.
Now, an international team of archaeologists, geophysicists and historians were able to confirm its existence using special Electrical Resistivity Tomography (ERT), a remote sensing technique, which detects changes in electrical properties underground. The technique is often used to find buried archaeological features, and through it the exact route of the tunnel could be identified.
Visitors to the site of Ponar, now known as Paneria, can now follow the trail which is marked by red flags.
