Yes, because bullying and shitty human behavior and mental health crises happen everywhere.
The big difference to take away from this incident is that this shooter had a handgun and there were "only" (still a fucking horror) a few people shot, vs in America where the shooter has body armor and assault rifles and dozens of people get shot.
I think the key factor here is that the shooter was 12 and incompetent. They're inferior to rifles but you can still kill a bunch of people with a handgun.
