Hillary Clinton, the Democratic candidate in last year’s presidential election, led calls on Monday for the American people to stand up to the powerful gun lobby in the wake of the country’s most deadly mass shooting.
Shares in firearm makers surged in early trading amid expectations of a spike in sales as gun enthusiasts rushed to beat any tightening of gun laws.
Mrs Clinton made her views clear on Twitter, criticising the stance of the National Rifle Association.
“Our thoughts are with the victims of these attacks and the city of Las Vegas,” said Margaret Huang, Amnesty International USA’s Executive Director.
“But thoughts must be backed up with actions to protect people from this kind of violence. No one’s life should be threatened just by walking down the street, going to school or attending a concert.
“The US government must uphold its obligations under international law and address gun violence as the human rights crisis that it is.”
Such calls prompted a rise in share price for companies like American Outdoor Brands, formerly Smith and Wesson, which saw a bump of almost five per cent in pre-market trading.
