A transatlantic flight that was diverted to Dublin Airport this morning because of a technical issue has declared another emergency.

American Airline flight AA55 made an unscheduled stop at Dublin shortly before midday after the crew reported a pressurisation issue.

The aircraft landed safely, but declared another emergency after resuming its journey at 4.15pm - reporting the same pressurisation problem.

The Boeing 767-300 jet with 181 passengers on board touched down again at Dublin Airport shortly before 5 O'clock.

Emergency services were standing by for the jet again.
