Polish lawmakers on Wednesday passed a controversial law that would make it illegal to refer to Nazi concentration camps as "Polish death camps." Widely speaking, the so-called Holocaust law makes it a crime to ascribe responsibility to Poles for crimes committed by Nazis during World War II. The law has caused diplomatic disputes between Warsaw and Israel, while the US government also urged Polish lawmakers not to pass the proposal. When the legislation comes into effect, such a reference made in Poland or abroad could lead to up to three years in prison.
