Romania — A Holocaust-era mass grave containing the bodies of an estimated 100 Jews killed by Romanian troops has been discovered in a forest, researchers said Friday, offering further evidence of the country’s involvement in wartime crimes.The find in a forest near the town of Popricani, some 350 kilometers (220 miles) northeast of Bucharest, contains the bodies of men, women and children who were shot dead in 1941, the Elie Wiesel National Institute for the Study of the Holocaust in Romania said in a statement. The find offers evidence of pogroms against Jews in the region, scholars say, campaigns that were long minimized in a country whose official history taught that Germans were the sole perpetrators of the Holocaust. Sketchy reports about the possibility of a mass grave in the forest began to appear in 2002, and local authorities began an investigation, which was suspended in the fall after nothing was found. Experts resumed the investigation at the site and began interviewing witnesses again in 2009. Some 280,000 Jews and 11,000 Roma, or Gypsies, were killed during the pro-fascist regime of dictator Marshal Ion Antonescu.
