Breaking on Drudge, who links to this BBC article:

Police and ambulances are attending the scene of a large blast in Mexico City, where at least one person is reported to have been killed and another hurt.
The blast occurred at about 1430 (2030 GMT) near the tourist area known as the Zona Rosa (Pink Zone), and the city’s police headquarters.

Police officers in riot gear swarmed about and cordoned off the area.

The cause of the explosion was unclear, though a senior police officer said it may have been an explosive device.

“Developing”, as Matt writes.
