An engineer has died after a jet crashed at a RAF Valley airbase earlier this afternoon.
The pilot was also injured and is receiving medical care.
The Red Arrows aircrew had been at RAF Valley for routine Hawk simulator training, which takes place once a month.
A spokesman from the RAF said:
It is understood the Red Arrows aircrew had been at RAF Valley for routine Hawk simulator training - something that takes place once a month.
They had just taken off from the base and were on their way back to RAF Scampton in Lincolnshire, where the aerobatic team are based, when the incident happened.
