Three troops from the Welsh Cavalry were among the first to help treat the victims of the Las Vegas shooting, in which scores were killed and hundreds wounded.

Ross Woodward, 24, was one of three troopers from the 1st The Queen’s Dragoon Guards who were in Nevada for a training exercise when gunman Stephen Paddock opened fire on concertgoers from the 32nd-floor of the Mandalay Bay hotel on Sunday.

At least 59 people were killed and a further 527 injured in the shooting spree, which lasted around 10 minutes and is now the deadliest in modern American history.
