Schools across the northeastern region of Catalonia have held five minutes of silence in memory of a teacher killed in a school attack by a 13-year-old boy armed with a crossbow and a machete.

The boy was detained by police as a suspect after the attack Monday morning in Barcelona that also saw two other teachers and two students injured.

Students and teachers gathered Tuesday for the midmorning silent ceremony inside the school in Barcelona's Sant Andreu neighborhood where the attack occurred.

Authorities said the boy, who is undergoing a psychiatric examination, will not face criminal charges because he is under the age of 14.

Catalonia's regional government declared a day of mourning and official institutions were to hold minutes of silence at midday.
