US President Donald Trump has announced a ban on “all devices” that turns semiautomatic guns into machine following mounting pressure over gun control following last week’s Florida school shooting.
Mr Trump said he had ordered Attorney General Jeff Sessions in a memo to ban the devices that include “bump stocks”, following protests for gun control action.
“Just a few moments ago, I signed a memorandum directing the attorney general to propose regulations to ban all devices that turn legal weapons into machine guns,” Mr Trump said while speaking a medal of valor ceremony at the White House.
“I expect that these critical regulations will be finalised…very soon.”
He said more effort was needed to prevent more deaths.
“The key in all of these efforts as I said in my remarks the day after the (Las Vegas) shooting is that we can not merely take actions that make us feel like we are making a difference, we must actually make a difference,” Mr Trump said.
“We must move past clichés and tired debates and focus on evidence-based solutions and security measures that actually work.”
“The Department of Justice said it was a priority for Mr Trump and it had “acted quickly to move through the rulemaking process.”
“We look forward to the results of that process as soon as it is duly completed.”
When connected to a gun, “bump stocks” enable a semiautomatic rifle to fire as quickly as a machine gun.
The device was found attached to a number of long guns found in a hotel room used by the shooter involved in the Las Vegas shooting in October.
58 people were killed in the shooting.
Mr Trump’s announcement came days after 17 people were killed at Marjory Stoneman Douglas High School.
There has been increasing pressure for action with students and parents affected by the massacre at the school planning a demonstration in the state capital Tallahassee on Wednesday.
White House spokesperson Sarah Huckabee Sanders said talks were ongoing and Mr Trump was not supportive of the use of bump stocks.
