On September 24, a group called Stop the Bomb protested in front of the European-Iranian Trade Bank headquarters in Hamburg. They demanded it be closed because of its involvement in Iran's military and nuclear programs.
Indeed, the U.S. government has been leaning on German Chancellor Angela Merkel to close down the bank's Hamburg operations, thus far to no avail. It's doubtful this protest will cause her to change her mind, given the importance of German-Iranian trade ties, but one can always hope. (Thanks to Michael.)
