German security staff are on strike at three airports today (10 January), disrupting tens of thousands of passengers’ travel plans.

Staff at Düsseldorf, Cologne-Bonn and Stuttgart have all walked out after members of the Verdi union voted in favour of industrial action.

In total, 623 flights have been cancelled as a result, according to German news agency dpa: 350 at Düsseldorf, 142 at Stuttgart and 131 at Cologne-Bonn.
