An American basketball coach has called for stricter gun control after the killing of 19 children and two teachers in a Texas school shooting.
Golden State Warriors coach Steve Kerr refused to talk about basketball at a pre-game press conference following the horror shooring on Tuesday.
Authorities said an 18-year-old gunman opened fire at an elementary school in south Texas, about 80 miles (130 km) west of San Antonio, before he was killed by police officers.
A visibly shaken Kerr, who has been an advocate of tighter gun laws, said he would not discuss the Warriors' Eastern Conference finals game against the Dallas Mavericks.
"Any basketball questions don't matter ... ," Kerr told reporters. "In the last 10 days, we've had elderly black people killed in a supermarket in Buffalo, we've had Asian churchgoers killed in Southern California.
"Now we have children murdered at school. When are we going to do something? I'm so tired of getting up here and offering condolences to the devastated families that are out there."
Kerr also criticised lawmakers for blocking efforts to advance gun control measures.
Small, rural, often Republican-led states where gun ownership is widespread have disproportionate influence in the U.S. Senate, where a supermajority of 60 votes is needed to advance most legislation in the 100-seat chamber.
"Do you realize that 90% of Americans, regardless of political party, want background checks, universal background checks? 90% of us," Kerr said.
"We are being held hostage by 50 Senators in Washington who refuse to even put it to a vote, despite what we the American people want. They won't vote on it because they want to hold on to their own power."
U.S. President Joe Biden has asked Congress to require new background checks for gun buyers and ban military-style "assault" weapons and large-capacity ammunition magazines.
Los Angeles Lakers' LeBron James also called for change.
"These are kids and we keep putting them in harms way at school," he wrote on Twitter. "Like seriously 'AT SCHOOL' where it's suppose to be the safest!
"There simply has to be change!"
