Security staff's strike will cause major disruptions at Germany's Frankfurt Airport on Thursday, the airport authorities cautioned. 

Security checkpoints will be closed on Thursday due to the strike and passengers departing from Frankfurt Airport will not be able to pass through the legally required security checks.

"The strike will cause major disruptions and flight cancellations throughout the day," the airport announced on X.

The airport advised passengers to contact their airline or travel operators regarding their flight schedule.

The union of the staff, Ver.Di, called a strike on Tuesday over wage negotiations.
