23 killed as metro overpass collapses on to road in Mexico City

An elevated section of the Mexico City metro has collapsed and sent a subway carriage plunging towards a busy road, killing at least 23 people and injuring about 70, city officials said.
Rescuers searched a carriage left dangling from the overpass for hours for anyone who might be trapped, but the effort was suspended early on Tuesday because of safety concerns. A crane was brought in to help shore it up.
