Today (April 19th) is the 70th anniversary of the uprising in Warsaw Ghetto. Hundreds of people came to the place where the ghetto was located during the war, honoring the armed revolt by Jews against Nazi German forces with ceremonies and the opening of a new Jewish History museum. Throughout Warsaw church bells rang and sirens sounded in tribute to the fighters who began the first and largest armed insurrection by Jews against the German troops in World War II on this day in 1943.
