Demonstrations across France have turned ugly as the country reaches its 10th day of civil unrest.

The backlash is in response to a controversial pension law pushed through parliament without a vote last week, lifting the retirement age from 62 to 64.

Europe Correspondent Gavin Grey told Kate Hawkesby protests started peacefully, but things have turned, with cars and rubbish being set alight, and 23 reported arrests.

He says Paris protest numbers are in dispute, with police claiming 93,000, while unions believe half-a-million protesters attended.
