Gay marriage law protesters march in Paris

Tens of thousands of people have rallied in Paris against a new French law allowing same-sex marriage.

Police estimate that up to 150,000 people joined marches that converged on the city centre, but organisers put the figure close to one million.

Clashes erupted after the rally finished between far-right activists and riot police. The authorities said nearly 100 people were arrested.
