Boy, aged six, shot dead by four-year-old friend in US

A six-year-old boy in New Jersey has died after being shot by a friend, aged just four, as their parents stood nearby.

Toms River police chief Michael Mastronardy said: "The six-year-old ... retrieved a rifle within the house, a .22-caliber rifle, came outside...

“A shot went out and the six-year-old was struck in the head."

The incident followed another fatal shooting days ago, this time in Tennessee, that also involved a four-year-old boy.
