GENEVA — The U.N.'s top human rights official says the U.S. breached international law when it executed a Mexican citizen.

U.N. High Commissioner for Human Rights Navi Pillay said Friday the Texas execution of Humberto Leal "raises particular legal concerns," including whether he had access to consular services and a fair trial.

Pillay also cited a 2004 International Court of Justice ruling saying the U.S. must review and reconsider the cases of 51 Mexican nationals sentenced to death, including Leal's - But, she said, that never happened.

Leal was executed Thursday despite a White House-backed appeal that claimed the case could affect foreigners arrested in the U.S.

and Americans in legal trouble abroad. Leal was sentenced to death for the 1994 rape and murder of a
U.S. teenager.
