Mexico's Interior Department said that the helicopter was carrying Secretary Alfonso Navarrete and Oaxaca state Governor Alejandro Murat, who were evaluating reports of damage from the powerful 7.2 magnitude quake, before their helicopter crashed.

Jorge Morales, a local reporter who was aboard the helicopter when it crashed Friday night, described harrowing moments as the pilot lost control and the helicopter attempted to touch down in a swirl of dust in Jamiltepec, a city in Oaxaca state close to the epicenter of the quake that struck earlier Friday.
On the north side of Mexico City, Julia Hernandez said she felt like she was "in a boat" as the ground swayed beneath her feet.

"Unfortunately, people on the ground lost their lives and others were wounded".
Oaxaca State Government tweeted: "We regret the loss of human life following an unfortunate helicopter accident in Jamiltepec, which was directed to carry out the supervision of damage caused by the natural disaster".
Efrain de la Cruz, mayor of Santiago Jamiltepec, was on the phone with CNN en Español's Mario González when the crash occurred. The department said the victims had been waiting for the helicopter, but did not provide more details.
"A helicopter is down, a helicopter is down".
A journalist on board the flight told local TV that the helicopter had flown in over a clearing next to homes, raising a huge dust cloud before it crash landed. "This can't be possible, oh my God".
