Far-right rally mars UN Climate Conference opening in Warsaw

The Polish capital, Warsaw, is currently hosting the United Nations Climate Conference. Last week's opening of the talks was overshadowed by a violent demonstration in the city. More than 50,000 attended a far-right march to mark Poland's Independence Day. The past year has seen the unification of two of Poland's largest far-right groups into a single "National Movement". Its ranks have been swelled by young people unhappy about unemployment and cultural change.
