<div><span style="font-size: 10pt;">US President Donald Trump has said his administration would take steps to ban an accessory that enables a rifle to shoot hundreds of rounds a minute as he considers additional firearms restrictions after last week's school shooting in Florida. Tightening gun laws would mark a change in course for Trump, who has championed gun rights during his campaign and presidency.&nbsp;</span></div>''<div><br />''</div>''<div>The mass shooting at a Parkland, Florida, high school – where 17 people were killed – has reignited a drive to curb access to firearms.&nbsp; Trump directed the US Justice Department to quickly complete a proposed rule that would treat &quot;bump stocks&quot; as machine guns, which could effectively outlaw them in the United States.&nbsp;</div>''<div></div>''<div>The move came in response to an October massacre in Las Vegas, where a gunman used a bump-stock-equipped rifle to kill 58 people. It put Trump at odds with the powerful National Rifle Association, which has opposed bump-stock restrictions and would allow him to bypass Congress, where a bump-stock ban has failed to advance.</div>
