Frankfurt, Germany this morning.

The organisers, a group called Blockupy – named after the Occupy Wall Street movement in 2011, estimated that about 10,000 demonstrators were at the rally. Thousands came into the German financial capital from other parts of Europe.

“Our protest is against the ECB, as a member of the troika, that, despite the fact that it is not democratically elected, hinders the work of the Greek government. We want the austerity politics to end,” Ulrich Wilken, one of the organizers, said. “We want a loud but peaceful protest,” he told Reuters.
