A young woman has died in hospital after being shot by a gunman who wounded 19 other people during a shooting spree at a Canadian college.
Some of the casualties are critical
The man was shot dead by police officers during a firefight on the campus in the city of Montreal.
Clad in black and carrying three weapons, the man entered the canteen of Dawson College during the lunch hour.
Some students fled in terror as he opened fire, while others barricaded themselves in classrooms.
The dead woman was in her 20s. At least six of the injured are in a critical condition in hospital.
Dawson College students described how the shooting began at about 1245 local time (1645 GMT), and how a total of 20 shots were heard over a half-hour period.
One witness described how the gunman, dressed in a black trench coat and military boots and with a Mohawk haircut, appeared emotionless as he fired his weapons.
"He said nothing. He had a stone cold face... He just started opening fire," one student said.
Others told of how he pursued terrified students along corridors and up stairwells.
Those who could not escape barricaded the doors to classrooms and hid themselves under their desks.
Initial reports quoting eyewitnesses suggested there had been more than one attacker and the gunman had committed suicide.
But Montreal's chief of police, Yvan Delorme, later said it had apparently been a single gunman who was apparently killed by police fire.
"For now, I am limiting it to one suspect who died after a police intervention on site," he said.
"The first policeman took charge of the situation, and shot in the direction of the suspect, and the suspect died."
Jose Rafael Heredia told the BBC News website: "I was in my calculus class when I heard three shots.
"Then one of my classmates saw through the window and started to say: 'Oh my God, oh my God.' Then everybody saw through the window, and we saw one guy on the floor bleeding... next to him was a girl that had been shot on her leg."
Canada's prime minister called the shooting "a cowardly and senseless act of violence".
"Our primary concern right now is to ensure the safety and recovery of all those who were injured during this tragedy," Stephen Harper said.
The shooting revived memories of a December 1989 attack in the city when a gunman shot and killed 14 young women in the Ecole Polytechnique, before turning the gun on himself.
