A German airport has been evacuated after a corrosive substance left 50 people with breathing difficulties, police said. According to German news agency dpa, emergency personnel were checking to see if any of the injured needed to be rushed to the hospital for treatment.
An airport in Hamburg, Germany, was evacuated after dozens were sickened by an unknown toxin Sunday afternoon.
Rene Schönhardt, spokesman for the Hamburg police, said there was "no evidence" that the incident was a terrorist attack.
The alarm was raised after reports of a strong smell in the airport and fire crews set up treatment centres for people complaining of irritation.
A source told Bild earlier that the unknown substance might have gotten into the airport's air-conditioning system.
The firebrigade that responded to the call set up first aid posts for those who had inhaled the substance.
Spokeswoman for the airport, Karen Stein, said: "We have cancelled all flights at least until 2pm, and most parts of the airport have been evacuated". It was not clear how the evacuation affected air traffic at the airport.
