The spokesman said a foot patrol unit of the Army was attacked by a mob, creating a life-threatening situation for the personnel.
He said the personnel opened firing in air, which could not have caused death of the youth.
The spokesman said there were intelligence inputs with regard to the plans by terrorists to entangle Army personnel, particularly in Baramulla, in a protest and to attack the Army taking shield of the crowd with a view to trigger large-scale violence.
"This needs to be probed in detail by police," the Army spokesperson said.
