Toronto police are investigating a stabbing at a high school after a 15-year-old student was wounded at the end of the school day on Wednesday.
The student was taken to hospital in critical condition following the attack that witnesses said began with a fistfight between two girls and ended with shots fired.
The 14-year-old girl who stabbed the 15-year-old student before taking her own life is believed to have been at her school for several months before the attack.

The school, Humber Oaks Community School, has about 750 students and 20 teachers. It had one break-out class, which was in the gym when it erupted into violence, according to witnesses who spoke to the Toronto Star.
On Thursday, Toronto police spokesman Mark Pugash said the school was closed for the remainder of the week.
Police were called to the school at 2.30pm. They said the fight between the two girls was so violent it turned into a stabbing and a shooting.
Emergency officials said two teenagers were in a critical condition, four students were being examined for non-life-threatening injuries, and the 15-year-old boy was treated for superficial stab wounds.
The school is a private school affiliated with the Christian academy, which employs a security guard 24 hours a day.
Det Insp Bradley Graham, who has led the Toronto homicide squad for more than two decades, told the Toronto Star the school on Wednesday evening.
He was told the fight stemmed from an argument between the girls in school, outside the school and on the school bus. Graham said one of the students involved was taken into custody and underwent a psychiatric evaluation.
