Cathay Pacific says one of its jets made an emergency landing in Kazakhstan after the cabin lost pressure.

Hong Kong’s main airline says the Boeing 747-400 landed at Karaganda airport in central Kazakhstan early Monday, six hours after the Hong Kong-bound flight left Amsterdam.

The airline said oxygen masks were deployed but the plane landed safely and the 306 passengers and 20 crew were unhurt.

Cathay said it has informed Hong Kong’s Civil Aviation Department about the incident.

The airline has sent another jet to pick up the stranded passengers and bring them to Hong Kong.
