OAXACA, Mexico -- A plane crash in southern Mexico killed all six people on board Friday, including two federal legislators and two mayors-elect.
Oaxaca state Public Safety Secretary Javier Rueda said the aircraft went down as it neared the airport in the Pacific coast beach town of Huatulco.
Reps. Guillermo Zavaleta and Juan Huerta were killed along with the mayors-elect of Huatulco and Juquila, another town in Oaxaca state, Rueda said.
Zavaleta and Huerta both belonged to the National Action Party of President Felipe Calderon, who issued a statement sending his condolences to the families.
The pilot and a local coffee grower were the other two people killed.
The plane took off from Mexico City on Friday morning. The cause of the crash was unknown, but authorities said inclement weather and possible pilot error were being investigated.
