MEMORANDUM ***

Gregory L. Brown, a California state prisoner, appeals pro se from the district court’s judgment in his 42 U.S.C. § 1988 action alleging Eighth Amendment violations arising from an assault by other inmates. We have jurisdiction under 28 U.S.C. § 1291. We review de novo. Lemire v. Cal. Dep’t of Corr. & Rehab., 726 F.3d 1062, 1074 (9th Cir. 2013) (summary judgment); Hamilton v. Brown, 630 F.3d 889, 892 (9th Cir. 2011) (dismissal under 28 U.S.C. § 1915A); Barren v. Harrington, 152 F.3d 1193, 1194 (9th Cir. 1998) (order) (dismissal under 28 U.S.C. § 1915(e)(2)(B)(ii)). We affirm.

The district court properly granted summary judgment for Lopez and Lantia because Brown failed to raise a genuine dispute of material fact as to whether they knew of and disregarded an excessive risk to Brown’s safety. See Farmer v. Brennan, 511 U.S. 825, 837, 114 S.Ct. 1970, 128 L.Ed.2d 811 (1994) (a prison official is deliberately indifferent only if the official knows of and disregards an excessive risk to an inmate’s safety; “the official must both be aware of facts from which the inference could be drawn that a substantial risk of serious harm exists, and he must also draw the inference”); see also Nelson v. Pima Cmty. Coll., 83 F.3d 1075, 1081-82 (9th Cir. 1996) (“[Mjere allegation and speculation do not create a factual dispute for purposes of summary judgment.”); Taylor v. List, 880 F.2d 1040, 1045 n. 3 (9th Cir. 1989) (to raise a triable dispute of fact a declarant’s statement must be based on personal knowledge).

The district court properly dismissed Brown’s claims against Clark and Reynoso because Brown failed to allege facts sufficient to show that they were deliberately indifferent to a substantial risk of serious harm to Brown. See Starr v. Baca, 652 F.3d 1202, 1207-08 (9th Cir. 2011) (explaining supervisory liability under § 1983); Hearns v. Terhune, 413 F.3d 1036, 1041-42 (9th Cir. 2005) (to state a failure-to-protect claim, plaintiff must make sufficient factual averments “to raise an inference that the prison officials acted with *697 deliberate indifference, or knew that [plaintiff] faced a substantial risk of serious harm, and disregarded that risk by failing to take reasonable measures to abate it” (citation and internal quotation marks omitted)).

AFFIRMED.
