"Our measures are intended to prevent and deter terrorist attacks. We will demonstrate strength and will not be intimidated. The public will be able to see these police measures, but there will also be many measures you will not be able to see," Maizière said in a statement today in Berlin.
Maizière said the Interior Ministry had "further relevant information" regarding potential Al Qaeda attacks on the United States and Europe, including Germany. "We have cause for concern, but no reason for hysteria. We will not allow international terrorism to interfere with our daily lives nor with our democratic way of life," he added.
