All flights in and out of Dublin Airport have resumed, after they were temporarily suspended this morning.

An issue with the radar system, operated by the Irish Aviation Authority (IAA), resulted in all services stopping from 8.20am until 9.35am.

The airport has said while operations have resumed, there 'll be knock on delays.

Passengers are being advised to check with their airline.

The IAA said: "The cause of the issue was identified by the IAA and a full air traffic control service has been restored."

It said it's satisfied the resulting backlog will be cleared today, and "regrets" any disruption.
