More than 30 Ryanair passengers, some bleeding from their ears, have received hospital treatment in Germany after their plane to Croatia lost cabin pressure, German police say.
Flight FR7312 from Dublin to Zadar made an emergency landing in Frankfurt.
The airline said oxygen masks were deployed and the crew carried out a "controlled descent".
The plane descended 8,000m (26,000ft) from 11,300m to 3,000m in seven minutes, according to Flight Radar.
