At least 13 people, including three children, have been killed after a Mexican military helicopter crashed in the southern state of Oaxaca. The chopper was carrying Mexico's interior minister and the state governor to survey damage from Friday's magnitude-7.2 earthquake. The officials survived the crash.
But the UH-60 Black Hawk helicopter crushed two vans in an open field. 12 people on the ground were killed and another died in hospital. 15 others sustained injuries.
