But the motive behind the attack is still unknown as cops continue their investigation.

“There is currently a major police operation in #Hamburg on #Hauptbahnhof!” Hamburg police said in a post on X.

“We are investigating the background and will provide further information here shortly.”

Dozens of police officers and first responders can be seen securing the scene outside Hamburg Central Station.

One victim of the Hamburg train station knife attack could also be seen being rushed in a stretcher by paramedics.

A Red Cross crisis response team is now on the scene to support the victims’ families.

It comes after two people were killed and two police officers wounded in a brutal knife attack in the Netherlands.

Emergency crews, including ambulances and trauma teams, raced to a property in Hoofddorp, near Amsterdam’s Schiphol Airport, on Wednesday morning.

One police vehicle at the scene was left spattered with blood.

Both victims were inside the house after initial reports of a “fight”.

Police confirmed two officers were injured but there was no immediate confirmation about the extent of their injuries.

Locals say the house, located on Fanny Blankers-Koenlaan, is known for drug and alcohol-related disturbances.

Local newspaper De Telegraaf also reported, citing multiple sources, that two people were killed in the stabbing spree.

Chilling images showed emergency vehicles lined up along the residential street in the aftermath of the deadly attack.
