Nobel Peace laureate and human rights advocate, Tawakkol Karman, has condemned the horrifying mass shooting in USA’s Las Vegas Sunday night, expressing deep sorrow to the American people. 

A 64-year-old man with multiple machine guns rained down gunfire from the 32nd floor of a Las Vegas hotel to country music festival on Sunday, slaughtering at least 58 people in the deadliest mass shooting in modern U.S. history before killing himself, said Reuters. 

Police on Monday identified the gunman as Stephen Paddock, who lived in a retirement community in Mesquite, Nevada. They said they believed he acted alone and did not know why he attacked the crowd. 

The Islamic State militant group has recently claimed responsibility for the massacre, but U.S. officials said there was no evidence of that.

"I share with the great American people the grief and pain caused by Las Vegas calamity," stated Tawakkol Karman on Facebook.
