German Interior Minister Nancy Faeser on Saturday vowed to fight a surge in violence against politicians after a German member of the European Parliament had to be taken to hospital after being attacked while campaigning for re-election. Matthias Ecke, 41, a member of Faeser's Social Democrats (SPD), was hit and kicked by a group of four people while putting up posters in Dresden, capital of the eastern state of Saxony, police said. An SPD source said his injuries would require an operation.
