The Iranian Foreign Ministry spokesman has extended his sympathies to the Americans over the “heinous crime” in Las Vegas, Nevada, the deadliest mass shooting in modern US history.

Bahram Qassemi on Tuesday offered sympathy to the American people, particularly the bereaved families of those killed in the recent deadly shooting in Las Vegas, Press TV reported.

He expressed regret over the “heinous” crime which killed tens of civilians and injured many others.

At least 59 people were killed and nearly 530 others injured when a gunman opened fire at a music concert in Las Vegas on Sunday night.

Retired accountant Stephen Craig Paddock, 64, carried out the deadliest mass shooting in US history at the open-air concert.

The gunman rained down bullets from the 32nd floor of the Mandalay Bay Resort and Casino for several minutes before shooting himself dead, according to police.

Law enforcement authorities have discovered an arsenal of weapons and ammunition from Paddock’s hotel room and house.

Las Vegas Police Department Assistant Sheriff Todd R. Fasulo said that 23 guns were found in Paddock’s hotel room, and 19 were discovered out of his home in Mesquite.
