There were incidents of violence in Berlin, Cologne and Hamburg, with police saying they used water cannon to disperse protesters who targeted emergency workers with fireworks, stones and bottles.

She said: "What matters most to us is better support for the health and education systems.
We are against compulsory military service and we are in favour of a fairer distribution of the burden." Europe's youth is on the march - but does anything actually unite them?

He added that it was "shameful" how the protests had ended.
Poseck said: "We all have those images from France in our minds – looting, burning houses, burning police vehicles, and attacks on police officers...
