A small group of demonstrators occupied the Athens headquarters of German industrial group Siemens on Monday, police and company officials said, in a protest against the austerity policies imposed on Greece by its lenders. About 30 people entered the building in a northern Athens suburb, occupying the Siemens offices and hanging a banner outside the main entrance ahead of a scheduled rally to the German embassy planned for later this month. The protesters also threw flyers saying: "We won't become a colony of Germany or any other Imperialist power". "It's a peaceful protest," Siemens Hellas spokeswoman Mari Agaliotou said.
