Attempted murder probe after petrol bomb thrown at French riot police

Youth-led protests end with street violence in cities across France, Germany, Switzerland, Portugal and Albania

French officials have opened an investigation into the attempted murder of a police officer and Germany's interior minister has called for harsh penalties after peaceful and mainly youth-led protests across Europe ended in violence.

In Portugal, police - some with dogs - cleared protest camps with baton charges, while security forces in Switzerland were attacked with paving stones.
