¶1 Deysi Yolanda Diaz petitions for review of the Board of Immigration Appeals’s *799 (BIA’s) decision denying her requests for asylum, withholding of removal, and relief under the Convention Against Torture (CAT). Substantial evidence supports the BIA’s determination that the gang violence Diaz experienced did not constitute past persecution or establish a well-founded fear of future persecution on account of her race, religion, nationality, membership in a particular social group, or political opinion; therefore, she has not shown an entitlement to asylum. See Lopez-Gomez v. Ashcroft, 263 F.3d 442, 444-45 (5th Cir.2001). Because Diaz has failed to satisfy the requirements for asylum, she has also failed to satisfy the requirements for withholding of removal under the Immigration and Nationality Act. See Girma v. INS, 283 F.3d 664, 667 (5th Cir.2002). Diaz has inadequately briefed the issue whether she is entitled to relief under the CAT, and it is therefore waived. See Soadjede v. Ashcroft, 324 F.3d 830, 833 (5th Cir.2003).
