MEXICO CITY (AP) " The death toll in the collapse of a parking garage under construction in Mexico City has risen to seven, and 10 other construction workers are being treated for injuries.
The city's civil defense office said late Monday the accident was apparently caused by errors made in the building process.
Photos of the collapse showed pre-fabricated concrete beams that had had fallen several stories.
Some workers were rescued from beneath the beams.
A statement from the government of Mexico's capital city says initial reports indicated the collapse came when a beam being raised by a crane struck a support column.
An investigation has been opened into the cause of the collapse and to determine if the construction project had the proper permits.
