One of Germany's largest train stations was evacuated and locked down Monday after a man took a woman hostage inside a pharmacy at the transportation hub, police said. "We're doing everything to get the hostage out of there unharmed", police spokesman Christoph Gilles said initially.
German railroad operator Deutsche Bahn said that all train traffic was shut down. DW's Dana Regev reported that two shots had been fired inside the station. The suspect was "seriously injured", however it's unclear if he was in police custody.
The attacker had to be resuscitated and was in intensive care for "extremely serious" injuries sustained when officers stormed the shop, they added.
