Pallade Veneta - Teen gunman kills 15 at Texas elementary school

The attack in Uvalde, Texas -- a small community about an hour from the Mexican border -- is the latest in a spree of deadly shootings in America, where horror at the cycle of gun violence has failed to spur enough action to end it.

Governor Greg Abbott, addressing a news conference, said the gunman was believed to have shot his grandmother before heading to Robb Elementary School at around noon, abandoning his vehicle and entering with a handgun, and possibly also a rifle.

"He shot and killed, horrifically and incomprehensibly, 14 students and killed a teacher," Abbott said.

The governor said the suspect, who he described as a local teenager and a US citizen, was also "deceased," adding that "it is believed that responding officers killed him."

Footage showed small groups of children weaving through parked cars and buses, some holding hands as they fled under police escort from the school, which teaches students aged around seven to 10 years old.

It was the deadliest such incident since 14 high school students and three adult staff were killed in Parkland, Florida in 2018 -- and the worst at an elementary school since the 2012 Sandy Hook shooting in Connecticut, in which 20 children and six staff were killed.

The White House ordered flags to be flown at half-staff in mourning for the victims -- whose deaths sent a wave of shock through a country still scarred by the horror of Sandy Hook.

President Joe Biden has been briefed on the shooting, and was to address the nation later on Tuesday.

Robb Elementary -- which teaches more than 500, mostly Hispanic and economically disadvantaged students from second through fourth grade -- called on parents not to pick up their children until all were accounted for.

"Please do not pick up students at this time. Students need to be accounted for before they are released to your care. You will be notified to pick up students once all are accounted for," the school said on its website.

- 'Nowhere else' -

Ted Cruz, a Republican US senator from Texas, tweeted that he and his wife are "lifting up in prayer the children and families in the horrific shooting in Uvalde."

But Senator Chris Murphy, a Democratic from Connecticut, where the Sandy Hook shooting took place, made an impassioned appeal for concrete action to prevent further violence.

"This isn't inevitable, these kids weren't unlucky. This only happens in this country and nowhere else. Nowhere else do little kids go to school thinking that they might be shot that day," Murphy said on the Senate floor.

"I'm here on this floor to beg, to literally get down on my hands and knees and beg my colleagues: Find a path forward here. Work with us to find a way to pass laws that make this less likely," he added.

The deadly violence in Texas follows a series of mass shootings in the United States this month.

On May 14, an 18-year-old white man shot 10 people dead at a Buffalo, New York grocery store.

Wearing heavy body armor and wielding an AR-15 rifle, the self-declared white supremacist allegedly livestreamed his attack, having reportedly targeted the store because of the large surrounding African American population.

The following day, a man blocked the door of a church in Laguna Woods, California and opened fire on its Taiwanese-American congregation, killing one person and injuring five.

Despite recurring mass-casualty shootings, multiple initiatives to reform gun regulations have failed in the US Congress, leaving states and local councils to enact their own restrictions.

The National Rifle Association has been instrumental in fighting against stricter US gun laws. Abbott and Cruz are listed as speakers at a forum that is being held by the powerful lobby in Houston, Texas later this week.

The United States suffered 19,350 firearm homicides in 2020, up nearly 35 percent compared to 2019, the Centers for Disease Control and Prevention (CDC) said in its latest data.
