Thousands of demonstrators are taking to the streets of Madrid, demanding better public pensions, as a wave of protests sweeps across several European countries amid heightened security and fears of fresh violence.
Organised by the pensioners' movement and supported by trade unions, including the General Confederation of Labour (CGT), the march is making its way from Atocha station through the Spanish capital towards Calle Alcalá, near Sevilla metro station.
