MEXICO CITY – As U.S. Secretary of State Condoleezza Rice arrived to meet Mexican leaders Thursday, Mexico’s attorney general pledged cooperation against terrorism while dismissing reports of terrorist activity on the U.S.-Mexico border….
Attorney General Rafael Macedo de la Concha also reiterated Mexico’s irritation at U.S. criticisms on crime, human rights, drug trafficking and security in Mexico. His remarks to a news conference at an anti-terrorism conference in Madrid were distributed to reporters in Mexico….
U.S. officials recently have expressed concerns that terrorists could slip across the vulnerable Mexican border into the United States, though they have said there is no evidence that has happened.
“Investigations we have conducted have shown that no such thing has occurred,” Macedo said. “Under no circumstances will Mexico allow our national territory to be a refuge for terrorists.”
