A 14-year-old boy has died after five high school football players were shot in a deadly "ambush" on Tuesday in Philadephia, according to police.
Philadelphia Police said in a statement that two gunmen opened fire following a football game at Roxborough High School, leaving 14-year-old Nicholas Elizalde dead.
The shots were fired from a light green Ford Explorer as players were walking off the field, according to police.
The statement added that Mr Elizalde was shot in the chest and pronounced dead in hospital at 5.09pm.
A 17-year-old was shot in the arm and three times in the leg, while another 14-year-old was hit once in the thigh. Police said another player suffered a graze wound. The details of the injuries suffered by the fifth victim have not yet been released.
Deputy Police Commissioner John Stanford said that no suspects have been publicly identified and the motive remains unknown.
He added that all of those struck by gunshots attend Roxborough, northwest of downtown Philadelphia.
He said: "The biggest piece of this - there's a 14-year-old dead who was doing what students do, having football games at the end of the day. "It's one of the things we encourage our kids to do."
