A five-year-old child was shot and killed by a teen who was filming a social-media video with friends, police said.
In the Minnesota incident, the five-year-old boy was in a house where several teens were making a video, police said in a Facebook post.
Police in the Brooklyn Park suburb said their initial investigation found the shooting to be accidental but added that the 13-year-old had been arrested and was being held at a juvenile detention center.
Separately, another five-year-old died in a shooting accident in the Atlanta suburb of South Fulton.
Family members told ABC affiliate WSB-TV that the young girl, identified as Khalis Eberhart, hit a gun sitting on a chair and it went off.
Neighbours said her father ran with her in his arms to arriving paramedics. Khalis, who was described as “a very smart girl,” was taken to hospital, but later died.
And in the third incident, police said a 25-year-old was having Thanksgiving dinner with his family when a stray bullet struck him, NBC reported.
Gun violence and homicides have soared in the US during the pandemic, making last year the deadliest in decades, with this year set to break that pace.
