Demonstrations have continued in Canadian city of Montreal despite the introduction of a new law aimed at ending three months of protests against proposed tuition fee increases.
More than 300 people were arrested and at least 10 injured injured on Monday, following clashes between protesters and police, authorities said.
But the new law has only served to fuel the student movement. Student groups have panned the law and said they would challenge it in court and continue demonstrations.
On Sunday night, protesters smashed store windows and opened a fire hydrant that flooded a downtown Montreal office building.
Authorities gave no estimate of the number of protesters, but local media said several thousand had gathered in central Montreal at the start of the demonstration.
