Tens of thousands of protesters have taken to the streets of Paris over plans to give gay couples in France the right to marry and adopt children.
Three big marches were converging on the Champs de Mars, next to the Eiffel Tower.
France’s Socialist government is planning to change the law this year.
But the demonstrators, backed by the Catholic Church and the right-wing opposition, argue it would undermine an essential building block of society.
The organisers put the number of marchers at 500,000, with demonstrators pouring into Paris by train and bus, although one government minister said the turnout was lower than they had predicted.
