Five trapped miners out of 14 are dead as a result of a gas explosion that occurred on 3 May 2011 at a small coal mine at Coahuila, Mexico.
Authorities had to wait until toxic gases dissipated enough to allow rescuers to begin exploring the mine's tunnels.
The rescue workers removed the bodies of the five miners from the mine on 4 May 2011 and the remaining nine are feared dead.
Mexican President Felipe Calderon has ordered the attorney general's office to open an investigation into the blast.
Mexico's foreign ministry said five Chilean specialists are expected to join the rescue operations at the mine to find the nine workers who remain trapped.
