In yet another shooting incident in the US involving toddlers, a six-year-old boy playing with his mother's gun accidentally shot and killed his four-year-old brother.
The older boy was playing with his mother's loaded gun at the family's third-floor apartment in New Jersey when he accidentally shot his brother in the head, Connie Jackson, a city spokeswoman, said.
The boy was taken to University Hospital in Newark where he was pronounced dead on Saturday, a hospital spokesperson was quoted as saying by CBS News.
The boys' mother, 22-year-old Itiyanah Spruill, was arrested later and charged with endangering the welfare of a child and a weapons violation. She was being held on $310,000 bail.
"This is a terribly unfortunate incident," Mayor Lester E Taylor III said in a statement.
"This is crazy because they should have a safe place," Vania image, a neighbour, was quoted as saying.
"Because that's been going on in the news over and over, where you hear about those incidents going on. So people should not have a gun around a four-year-old and a six-year-old," Limage said.
City police and investigators with Essex County's Major Crimes Task Force were investigating the shooting.
The incident was the latest in a slew of shootings in the US involving toddlers.
A 5-year-old girl in Detroit last month died after she shot herself with a gun she found under her grandmother's pillow.
Also last month, a five-year-old girl accidentally shot herself dead while playing with her father's handgun in Lousiana.
