MEXICO CITY -- Four people were shot to death in the Mexican capital Saturday, just steps from an entrance to the official residence of the president, authorities said.

Officials said a man entered an apartment building near the National Palace seeking to urinate in the courtyard and was confronted by residents. He pulled out a gun and began shooting, hitting five people, officials said.

Residents who declined to give their names said their street in the capital's historic center is far from safe, despite being a stone's throw from the National Palace. President Andres Manuel Lopez Obrador moved into the palace when he took office a year ago, turning the former presidential residence in Chapultepec Park into a museum.
