ABC Radio News (June 10th) reported a gunfight at an all-night art festival that took place in Trenton, New Jersey. It said:
Police say one gunman was killed, and other is in custody, seventeen other people were shot and wounded. Five people suffered non-gun-shot injuries.
Then one hour later it reported again:
One of two gunmen is dead. The other is in custody. Authorities say a total of 17 people suffered gun-shot wounds.
Cambridge online dictionary defines wound and injury as:
Wound: a damage area of the body such as a cut or hole in the skin or flesh body by a weapon.
Injury: physical harm or damage to somebody’s body caused by an accident or an attack.
Based on Cambridge dictionary, it seems that “wound” is basically associated with use of weapon, and “injury” is associated with accident (or attack which doesn’t necessarily require the use of weapons).
Though it may seem a very naïve question to most of native English speakers, I wonder what the basic difference is between “wound” and “injury” - the presence of weapons, accident, or what else?
