WASHINGTON — US President Joe Biden and his Attorney General Merrick Garland announced limited measures to tackle gun violence in the United States on Thursday (April 8) in what the White House described as a first step to curb mass shootings, community bloodshed and suicides.

The new measures include plans for the Justice Department to crack down on self-assembled "ghost guns" and make "stabilising braces" — which effectively turn pistols into rifles — subject to registration under the National Firearms Act.

Mr Biden said he will ask the Bureau of Alcohol, Tobacco, Firearms and Explosives to release an annual report on firearms trafficking in the United States, and make it easier for states to adopt "red flag" laws that aim to prevent individuals deemed to present a danger to themselves or others from owning guns.

Mr Biden also outlined more ambitious goals that he needs the support of Congress to accomplish, including reintroducing a ban on assault weapons, lifting an exemption on lawsuits against gun manufacturers, and passing a nationwide red flag law.

The executive orders unveiled on Thursday are not legislative. The White House promised that more action was coming.

"Today we're taking steps to confront not just the gun crisis, but what is actually a public health crisis," Mr Biden said, speaking in the Rose Garden to an audience filled with family members of victims of gun violence.

He noted another mass shooting in South Carolina this week.

"This is an epidemic, for God's sake, and it has to stop," Mr Biden said.

Advocates for gun restrictions welcomed the measures.

"This is a significant set of actions," said Mr Peter Ambler, executive director of Giffords, a gun violence prevention group, praising Mr Biden for promising to do more. "Some of the most important words that he uttered were: This is just the start."

Mr Biden, a Democrat who has a long history of advocating for gun restrictions, has come under pressure to step up action after recent mass shootings in Colorado and Georgia.

Mr Biden announced the measures alongside Vice President Kamala Harris and Mr Garland, whom Mr Biden said would prioritise gun violence as head of the Department of Justice (DOJ).

"We've had more tragedy than we can bear," Madam Harris said. "People on both sides of the aisle want action... So all that is left is the will and the courage to act."

The DOJ will issue a proposed rule on ghost guns in 30 days, and proposed rules on stabilising braces within 60 days.

Mr Garland said the department will also be rethinking the way that it analyzes criminal cases and investigations to try learn more about modern gun-trafficking patterns.

Gun control is a politically divisive subject in the United States, which has experienced a significant number of deadly mass shootings at schools and other public venues for decades.

The US Constitution's Second Amendment protects the right to bear arms, and state attempts to limit who can buy guns or how they can carry them have been challenged in court by pro-gun lobby groups.

The most prominent of those groups, the National Rifle Association, criticised the measures.

"The proposals Biden announced today could require law-abiding citizens to surrender lawful property and enable states to expand gun confiscation orders," it said in a statement.

Most Americans support strengthening US gun laws. An overwhelming majority support expanding background checks and keeping guns from the mentally ill, polls by Reuters and others show.

A series of gun control measures have failed in Congress, however.

"Enough prayers. Time for some action," Mr Biden said on Thursday, asking Congress to pass a proposed bill requiring background checks at gun shows and online.

"Everything that is being proposed today is totally consistent with the Second Amendment," Mr Biden said. "And there's a wide consensus behind the need to take action." REUTERS
