A newly opened shopping mall on Mexico City’s south side partly collapsed due to structural problems. A video captures the moment the cantilevered, multi-story section of the mall collapses in a cloud of dust, smashed glass and twisted metal.

The Artz Pedregal mall opened in March, though parts remain under construction. It had drawn the ire of neighbors worried about the loss of open space, congestion and other issues. Built on the edge of the city’s main expressway, the mall had suffered previous subsoil slides.

The city also has notoriously bad subsoil conditions, and developers often build on unstable land.

In 2016, while foundation work was still being done on the mall, a retaining wall next to the expressway partly collapsed.
