Mexican Assassination

MEXICO CITY -- The secretary-general of Mexico's ruling party, Jose Francisco Ruiz Massieu, was assassinated Wednesday in front of a downtown hotel.

A young man was arrested at the scene but officials gave no identity or motive.

The killing shocked officials still recovering from the March 23 assassination of ruling party presidential candidate Luis Donaldo Colosio, shot at a Tijuana campaign rally. His successor, Ernesto Zedillo, won the Aug. 21 presidential election and takes power Dec. 1.

Mexico had been shaken this year not only by Colosio's killing and the New Year's uprising by rebels in southern Mexico, but a wave of kidnappings of businessmen and narcotics-related violence.

Deputy Attorney General Mario Ruiz Massieu, the slain man's brother, announced the death. He is in charge of prosecuting drug traffickers for the federal attorney general's office.
