Protesters surged forward before tear gas was fired

Five Ligue 1 matches have been postponed - with another three rearranged - because of the security issues in France as games are called off for the second weekend in a row.
The country has seen four weekends of violent anti-government protests - with more demonstrations expected.
Paris St-Germain's game in Dijon on Saturday is one of those postponed.

A minute's silence will be held before the games to honour the victims of the unrelated shooting in Strasbourg.
Strasbourg's players - whose game at Reims on Saturday goes ahead - will wear a shirt without sponsors' logos to pay respect. Three people were killed, with a fourth left brain dead and 12 others wounded in a Christmas market gun attack.
