Before BUTTLER, P.J., and WARREN and ROSSMAN, JJ.
WARREN, Judge.
In this negligence case, plaintiff appeals from a judgment dismissing his complaint on the ground that it fails to allege facts adequate to state a claim. We affirm.
When considering a dismissal for failure to state a claim, we assume the truth of all factual allegations in the complaint and any facts that might fairly be adduced as proof of the allegations. Brennen v. City of Eugene, 285 Or. 401, 405, 591 P.2d 719 (1979); Hilt v. Bernstein, 75 Or. App. 502, 509, 707 P.2d 88 (1985) rev. den. 300 Or. 545, 715 P.2d 92 (1986). Conclusions are disregarded. Baker Hotel v. Employees Local 161, 187 Or. 58, 64, 207 P.2d 1129 (1949); Mattoon v. Cole, 172 Or. 664, 669, 143 P.2d 679 (1943).
Plaintiff's amended complaint alleges that, while he was attending a girls' basketball game sponsored by defendants, he was injured when three students from Amity High School attacked him. He also alleges:

*444 "IV
"Students from both schools were invited to attend this basketball game. Neither school districts provided any supervisory personnel within the gymnasium, other than the coaches of the respective teams. Neither school districts stationed any of its employees at the entrance to the gym.
"V
"The agents and employees of the school districts knew or should have known that there is a substantial risk of fighting among unsupervised students of rival high schools at athletic events. The agents and employees of each school district knew or should have known that failure to provide adequate supervision of the minor children attending the basketball game would create an unreasonable and unavoidable risk of injury to such minor children, and each of the defendants were [sic] negligent in failing to provide adequate supervision of the students of the rival high schools attending this basketball game."
To state a claim in negligence, a plaintiff must allege facts, as distinguished from conclusions, that show that the defendant owed a duty of care, that the defendant breached the duty and that the breach was the cause in fact of some legally cognizable damage to plaintiff. Brennen v. City of Eugene, supra, 285 Or. at 405, 591 P.2d 719. The duty to prevent harm to another arises from a relationship between the actor and the other which gives to the other a right to protection. Restatement (Second) Torts § 315 (1965); Cramer v. Mengerhausen, 275 Or. 223, 227, 550 P.2d 740 (1976); Sullenger v. Setco Northwest, 74 Or. App. 345, 348, 702 P.2d 1139 (1985). The existence of a duty is a question of law for the court. See Dewey v. A.F. Klaveness & Co., 233 Or. 515, 524, 379 P.2d 560 (1963) (O'Connell, J., specially concurring).
Defendants, as possessors of land held open to the public and due to their special relationship with the students who attend their schools, had a duty to take precautions to protect plaintiff from reasonably foreseeable acts of third parties. Fazzolari v. Portland School Dist. No. 1J, 78 Or. App. 608, 611, 717 P.2d 1210, rev. allowed 301 Or. 338, 722 P.2d 737 (1986). Plaintiff adequately alleges the relationship from which the responsibility to prevent harm flows.
To determine whether plaintiff alleges a breach of that duty depends on whether the facts stated in the amended complaint show that, as a result of defendants' acts or failure to act, plaintiff sustained harm that was foreseeable in the context posed by the complaint. See Brennen v. City of Eugene, supra, 285 Or. at 405-06, 591 P.2d 719; Sullenger v. Setco Northwest, supra, 74 Or. App. at 348, 702 P.2d 1139. In other words, although school authorities, because of their relationship to students, have a duty of care and supervision, it does not extend to unforeseeable harm any more than does the duty of anyone. Grant v. Lake Oswego Sch. Dist. No. 7, 15 Or. App. 325, 333, 515 P.2d 947 (1973).
The role of the court in determining whether an injury was foreseeable is set out in Stewart v. Jefferson Plywood Co., 255 Or. 603, 604, 469 P.2d 783 (1970):
"The specific question before us is, then, whether plaintiff's injury and the manner of its occurrence was so highly unusual that we can say as a matter of law that a reasonable man, making an inventory of the possibilities of harm which his conduct might produce, would not have reasonably expected the injury to occur. Stated in another way, the question is whether the circumstances are out of the range within which a jury could determine that the injury was reasonably foreseeable." (Footnote omitted.)
See also Rosensteil v. Lisdas, 253 Or. 625, 456 P.2d 61 (1969) Plaintiff's amended complaint fails to allege any facts which could cause a reasonable person to believe that a failure to provide supervision would make an unprovoked attack by other students likely. The complaint contains no allegations that there had been prior assaults or misconduct by students at other athletic events. Similarly, there are no allegations *445 to indicate that the basketball game in question would be likely to inspire violence. It cannot be said as a matter of law that violence is the natural attendant of attending a basketball game or that the districts should have foreseen that violence would occur at this particular game.
General conclusory allegations that defendants knew or should have known that there was a substantial risk of violence, in the absence of ultimate facts upon which the allegation is based, are insufficient to withstand a motion to dismiss. See Davis v. Tyee Industries, Inc., 295 Or. 467, 479, 668 P.2d 1186 (1983). The trial court properly dismissed the complaint for failure to state a claim.
Affirmed.
BUTTLER, Presiding Judge, specially concurring.
Although I agree that the complaint does not allege sufficient facts to state a claim, I do not agree that the allegations are sufficient to permit the court to say, as a matter of law, that defendants had a duty to plaintiff to prevent the harm claimed. If a duty is alleged, as the majority says, then I think the question whether there was a breach of that duty is for the jury, in which case the trial court erred in granting defendants' motion to dismiss.
In the abstract, every person owes a duty to exercise due care. The majority does not, apparently, rely on that abstraction. It says:
"Defendants, as possessors of land held open to the public and due to their special relationship with the students who attend their schools, had a duty to take precautions to protect plaintiff from reasonably foreseeable acts of third parties. Fazzolari v. Portland School District No. 1J, 78 Or. App. 608, 611, 717 P.2d 1210, rev allowed 301 Or. 338 [722 P.2d 737] (1986)." 83 Or. App. at 295, 731 P.2d at 444 (Emphasis supplied.)
As I said in my dissent in Fazzolari,[1] I agree that defendants had a duty to protect plaintiff from foreseeable risks. Yet the majority, after making the quoted statement, does not treat foreseeability of harm as a consideration in deciding whether defendants owed a duty to plaintiff. 83 Or. App. at 295, 731 P.2d at 444. (Slip opinion at 3.) Rather, it treats foreseeability as relevant only to the question of whether there was a breach of duty. As I have indicated, I think that that is wrong, although foreseeability is also relevant to that question. Whether there is a duty is a question for the court; whether there is a breach of that duty is for the jury. We should not confuse further an already complicated and confusing area of the law.
Because I conclude that plaintiff has not alleged sufficient ultimate facts to permit the court to hold that defendants had a duty to him in the circumstances alleged, I concur that the trial court should be affirmed.
NOTES
[1]  Without repeating all that I said in my Fazzolari dissent, I do not agree with the majority that the fact that one of the defendants was a possessor of land held open to the public affects either defendant's duty; that rule is not applicable to school districts, which are non-commercial enterprises.
