Thousands of protesters are gathering across the US to call for stricter gun laws in the wake of last month’s mass shooting in Texas.
Gun safety group March For Our Lives – founded by survivors of the 2018 Parkland school shooting – said some 450 rallies were planned for Saturday.
It said it would not let politicians “sit back” as people continue to die.
US President Joe Biden backed the protests, calling on Congress to “pass common sense gun safety legislation”.
Nineteen children and two adults were killed in the 24 May shooting at Robb Elementary in Uvalde, Texas.
That attack, and another days earlier in Buffalo, New York, in which 10 people were killed, has led to renewed calls for action on gun control in the US.
March For Our Lives (MFOL) said political leaders’ inaction was killing Americans.
“We will no longer allow you to sit back while people continue to die,” Trevon Bosley, a MFOL board member, said in a statement.
Among other policies, MFOL has called for an assault weapons ban, universal background checks for those trying to purchase guns and a national licensing system, which would register gun owners.
Rallies are being held in cities including Washington, New York, Los Angeles and Chicago.
The first MFOL protest was held days after the Marjory Stoneman Douglas high school shooting in Parkland, Florida, in 2018, in which 14 students and three adults were killed. Organisers say it was the largest gun safety rally in one day in US history, and thousands of students across the country left their classrooms to join the demonstrations.
Mr Biden, a Democrat who this month urged Congress to ban assault weapons, expand background checks and implement other gun control measures, said he supported Saturday’s protests.
Today, young people around the country once again march with @AMarch4OurLives to call on Congress to pass commonsense gun safety legislation supported by the majority of Americans and gun owners.
I join them by repeating my call to Congress: do something.

In recent weeks, a bipartisan group of Senate negotiators have vowed to hammer out a gun control deal, though they have yet to reach an agreement.
Their effort is focused on relatively modest changes, such as incentivising states to pass “red flag” laws that allow authorities to keep guns from individuals deemed a danger to others.
But Republican opposition in the Senate means the bill has little chance of entering law.
