Battles between England and Russia fans were followed on Sunday by clashes between Germany and Ukraine, leading to strict measures from the host nation
The French government has banned alcohol in fan zones and "sensitive areas" on match days following the violent scenes that have marred the start of Euro 2016.
Police had to use tear gas and water cannons to try and deal with clashes between supporters of England and Russia, as well as local gangs, over the past three days in Marseille. There have also been incidents in Nice, where Northern Ireland played Poland on Sunday, and Lille, the venue for the Group C fixture between Germany and Ukraine.
