Chaotic scenes unfolded at Germany's Frankfurt airport in the early hours of Thursday after severe flooding from heavy rainfall caused flight cancellations and delays.
Video footage showed long snaking queues at the airport's departure area, with some travelers seated on the floor after the flooding caused some 70 flights to be canceled, according to the Frankfurt Airport website.
Severe weather warnings had been issued by the German Weather Service (DWD) throughout the state of Hesse on Wednesday, with up to 60 litres per square meter of rainfall recorded in parts of the region in the evening.
