U.S. President Joe Biden called for a "ban" on the sale of assault rifles to individuals in a televised speech nine days after a horrific massacre of 19 children and two schools at a Texas school.
"How many massacres do we have yet to endure?" he asked, appearing to be impressed. He stressed the need to raise the minimum age for the purchase of these weapons, currently set at 18 years, to 21 years.
Biden condemned the refusal of a majority of Republican senators to adopt stricter gun laws in the United States, calling it "unacceptable."
"It's time for the Senate to do something," he said in his address to the nation, adding that lawmakers "can't let the American people down again."
On Thursday, five people were injured in a shooting at a cemetery in the northern US state of Wisconsin during the burial of a man killed in late May by police, security forces and a local channel reported.
Thursday's incident came a day after a shooting at a hospital in Tulsa, Oklahoma, killed four people, and less than 10 days after a massacre of 19 children and two teachers at a school in Yuvaldi, Texas.
Since the Yuvaldi massacre, there have been more than 20 shootings in which many victims have been killed in the United States, according to Gun Fuels Arkaev.
