Gun violence continues as US celebrates Independence Day

Mass shootings in Philadelphia, Baltimore, and Fort Worth, Texas, have claimed the lives of 10 people ahead of the Fourth of July holiday, officials said, a grim reminder of the decades-long failure to curb gun-fuelled violence in the United States.

In Fort Worth, three people were killed and eight wounded in a mass shooting following a local festival, police said on Tuesday.

In a separate mass shooting incident in Philadelphia on Monday evening, five people were killed, and two were injured when a suspect in a bullet-proof vest opened fire on apparent strangers, according to local police.

A toddler and a teenager were among the wounded.

The Monday night shootings came a day after two people were shot dead and 28 others injured, about half of them children, in a hail of gunfire at an outdoor neighbourhood block party in Baltimore.

On Tuesday, US President Joe Biden condemned the violence and renewed his calls to tighten America's lax gun laws.

"Our nation has once again endured a wave of tragic and senseless shootings," the president said in a statement.

"As our nation celebrates Independence Day, we pray for the day when our communities will be free from gun violence."

Biden called on Republican lawmakers "to come to the table on meaningful, common sense reforms."

At a Fourth of July parade last year in Highland Park, Illinois, just outside Chicago, a gunman killed seven and wounded dozens. This year, the suburb planned a remembrance ceremony in lieu of a parade and traditional festivities, officials said.

"In mere moments, this day of patriotic pride became a scene of pain and tragedy," Biden said in reference to the shooting's anniversary.

Motives unknown

Republicans in Congress have generally blocked attempts to significantly reform gun safety laws and oppose Biden's push to reinstate a ban on assault weapons.

The motives in all three recent shootings were not immediately clear.

Philadelphia Police Commissioner Danielle Outlaw said her force had arrested a suspect, identified as a 40-year-old man who had an assault-style rifle, among other weapons.

She said at a late-night news conference that "we have absolutely no idea why this happened."

The city's district attorney, Larry Krasner, told The New York Times on Tuesday that the killing spree "seems to bear the characteristics of a lot of random mass shootings that happen in the United States."

Police in Fort Worth said no arrests have been made in that shooting.

"We don't know if this is domestic-related, if it is gang-related. It is too early to tell at this point," said Shawn Murray, a senior police official.

Police have said they are seeking multiple suspects in the Baltimore shooting incident.

Mass shootings near record in 2023

The United States has been struggling with a large number of mass shootings and incidents of gun violence.

There have been over 340 mass shootings so far in 2023 in the country, according to data collected by the Gun Violence Archive, which defines a mass shooting as an incident in which at least four people are shot, excluding the shooter.

At the pace of the first half of this year, mass shootings over the 2023 calendar year would reach 679 or about double the 336 recorded in 2018.

That would mark the second-highest annual total over the last nine years, behind only the 690 recorded in 2021, according to the non-profit group.

The United States has by far the most gun deaths per capita of any large high-income country, analysis from the University of Washington's Institute for Health Metrics and Evaluation shows.
