The hunt for witches in Norway's icy circle of hell

Between 40,000 and 50,000 people were killed during Europe's 16th and 17th century witch hunts. Some of the most ferocious persecution took place in tiny communities in the remote Arctic Norwegian county of Finnmark. Now their personal stories are being retold in a giant monument commemorating those who were killed. Lars Bevanger reports from the Arctic Norwegian town of Vardoe.
