Emergency crews are cleaning up after a storm bearing record-breaking winds left at least one person dead and more than a million without power across the island of Ireland and Scotland.

The storm had knocked out power to more than half a million utility customers by early Friday as it moved across Ireland.

Record high winds from Storm Eowyn battered Ireland and Northern Ireland on Friday, leaving one man dead and almost one-third of Irish homes and businesses without power and forcing the cancellation of hundreds of flights.
