President Donald Trump has described the gunman who killed 59 people and injured 527 in Las Vegas on Sunday as “a sick man, a demented man”.

Speaking at the White House, he said he would look at gun laws “as times goes by” but did not elaborate.

Police are still trying to find out why Stephen Paddock, 64, opened fire on an open-air concert from the 32nd floor of the nearby Mandalay Bay Hotel.

Police found 23 guns in his room and firearms and explosives at his home.

Photos from the hotel room of guns used in the attack have been obtained by Boston 25 News.
