The Mexican government says it "strongly rejects" the scheduled execution in Texas of a Mexican man convicted of killing a police officer.
A statement by the Foreign Relations Department released Sunday say that executing Edgar Tamayo would be another U.S. violation of an international treaty.
Tamayo is set for lethal injection Wednesday for the 1994 fatal shooting of a police officer who had arrested him for a robbery.
Mexico has been asking the United Sates to halt Tamayo's execution because the inmate wasn't told he could get legal help from the Mexican government as agreed under the 1963 Vienna Convention on Consular Relations.
Tamayo's lawyers say assistance from the Mexican consulate could have helped Tamayo obtain mitigating evidence to persuade jurors to choose a punishment other than death.
