LATEST: As he prepared to travel to Las Vegas, Donald Trump said it was a "sad day".

“I ended up in the kitchen of the Irish bar in the hotel. My mam and dad and mother-in-law where under tables. Everyone was screaming, running and crying."

The Las Vegas shooter Stephen Paddock was a big-spending gambler who was found dead with as many as 10 guns in his hotel bedroom after the deadliest mass shooting in US history.

“He saved my life and lost his,”

The Department of Foreign Affairs issued a contact number for families in Ireland who have concerns about relatives to ring the consular assistance unit on +353 1 408 2527.

The gunman responsible for the worst mass shooting in modern US history is believed to be a grandfather who lived in a remote desert home.
