PER CURIAM.
Guatemalan citizen Tomas Tarce petitions for review of an order of the Board of Immigration Appeals (BIA) affirming an Immigration Judge’s (IJ’s) denial of his application for asylum, withholding of removal, and relief under the Convention Against Torture (CAT).
After careful review of the record, we conclude the decision of the IJ and the BIA — that Tarce failed to establish either past persecution or a well-founded fear of future persecution on account of a protected ground — is supported by substantial evidence in the record as a whole. See Eta-Ndu v. Gonzales, 411 F.3d 977, 982-83 (8th Cir.2005) (standard of review); see also Quomsieh v. Gonzales, 479 F.3d 602, 605 (8th Cir. 2007) (when BIA adopts IJ’s decision and adds its own reasoning, this court reviews both decisions together). Because Tarce alleged the same factual basis for all his claims, the conclusions that support the denial of his asylum claim also support the denial of his withholding-of-removal and CAT claims. See Samedov v. Gonzales, 422 F.3d 704, 708-09 (8th Cir.2005).
Accordingly, we deny the petition.
