Four people are dead after a cargo train, notorious for transporting Central American people hoping to get to the United States, derailed in southern Mexico.
At least 35 people were injured, 16 were gravely hurt, and officials say the death toll is expected to rise, the BBC reports.
An unknown number of people were also trapped.
The derailment occurred in the early hours of Sunday morning in a place surrounded by lakes and forest, with no mobile phone coverage.
Mr Burelo said dozens of people had been on the train, which was moving north from the border of Guatemala.
The train, sometimes called "the beast", often carries hundreds of people on the roof as they undertake the risky journey to the US.
