Following two horrific shootings last month, the first at an elementary school in Texas killed 19 children and two teachers, and the second at a supermarket store in New York killed 10 black people.

Thousands of people are expected to take part in demonstrations across the United States calling for tighter arms controls to end the country's armed violence.

There have been calls for Saturday's protests to be held in hundreds of places.

But the problem of armed violence that has so far killed more than 19 thousand and 300 people in the United States this year, according to the Armed Violence Archive, goes beyond mass murders of great interest and follow-up, the majority of deaths resulting from suicide.

The March for Orleaves Association, which organizes events on its website, announced that, after mass shootings and countless cases of armed violence in our communities, it was time to return to the streets. "

She stressed that the move was aimed at "understanding our elected officials that we demand and deserve a nation free from armed violence".

The survivors of a shooting at a Parkland high school in Florida founded the March for Orleaves Association, which had organized in March 2018 in Washington, D.C., an event involving thousands of people.

The association's founder and board member David Hough invited Americans from various party affiliations to participate in the protests scheduled for Saturday.

While mass killings have provoked widespread outrage in the United States, where the majority of the population supports tighter gun sector controls, opposition from many Republican members of Congress remains an impediment to major changes.

This week, the House of Representatives, where the majority of Democrats have a package of proposals, including raising the legal age to buy the majority of half-automatic rifles from 18 to 21, passed, but the party does not have the majority of the 60 votes needed to sustain the package in the Senate.

A bipartisan group of senators is working on a limited package of controls that could turn into the first serious attempt in decades to reform the arms sector's sponsors.

The package includes increased allocations for the mental health care sector and school security, expanded verification of the existence of precedents among those wishing to purchase weapons and incentives for states to enforce "red flag laws" that empower authorities to confiscate weapons from persons deemed to be a source of threat.

But it does not include a ban on assault weapons or a thorough scrutiny of precedent, and will therefore remain below what U.S. President Joe Biden, progressive members of the Democratic Party and anti-armed violence activists hope.
