An overpass carrying a subway train collapsed in Mexico City late Monday, killing at least 24 people and injuring more than 70, according to local government officials.

The train was traveling on an elevated and outdoor portion of the newest Line 12, also known as the Golden Line, when a portion of the overpass collapsed, Mexico's Secretariat of Risk Management and Civil Protection said.

The incident happened at 10:25 p.m. local time, according to Mexico City's Interior Minister Alfonso Suarez Del Real.

International engineering experts will be called in to help determine the cause of the collapse, which the country's foreign minister, Marcelo Ebrard, called "the most terrible accident we've ever had in the public transport system."

The collapse happened near Olivos Station at 10:25 p.m. on Monday, according to Mexico City's Interior Minister Alfonso Suarez Del Real.
