A section of mountain on the outskirts of Mexico City has given way, plunging rocks the size of small homes onto a densely populated neighbourhood and leaving at least one person dead and 10 others missing.
Firefighters on Friday scaled a three-storey pile of rocks that appeared to be resting on houses in Tlalnepantla, which is part of Mexico state. The state surrounds the capital on three sides.
As rescuers climbed the immense pile of debris, they occasionally raised their fists in the air, the familiar signal for silence to listen for people trapped below.
Firefighters and volunteers formed bucket brigades to pass containers of smaller debris away as they excavated.
"In this moment our priority is focused on rescuing the people who unfortunately were surprised at the site of the incident," said Tlalnepantla Mayor Raciel Perez Cruz in a video message.
Rescuers carried a body on a stretcher covered with a sheet past AP journalists. The Mexico state Civil Defence agency said at least 10 people were missing.
The landslide follows days of heavy rain in central Mexico and a 7.0-magnitude earthquake Tuesday night near Acapulco that shook buildings 320 kilometres away in Mexico City.
