Thousands of undocumented migrants continue to cross into Germany every day despite tighter controls that Berlin reintroduced on the border with Austria. Bavarian authorities stopped short of threatening to seal the border.
"If the federal government fails to intervene, the Free State of Bavaria reserves the right to adopt it own measures," Herrmann warned, as quoted by Bavarian Radio (BR).
Bavaria is the entry point for hundreds of thousands of economic migrants, and refugees from Africa and the Middle East that have come to Germany since the start of the year. According to Bavarian authorities, some 225,000 refugees arrived in Bavaria between September 1 and October 3.
