The fiery wave of blasts occurred earlier this week at a market in Tultepec outside Mexico City, killing at least 26 at the scene and now a total of 10 at hospitals.

Of the 60 hurt in the explosions several remain in critical condition, according to authorities.

At the time of the blast the market was packed with customers buying pyrotechnics for traditional year-end festivities.

Christmas and New Year parties in many Latin American countries often wrap up with a fireworks free-for-all.

The market had been rocked by two explosions in the past: in September 2005 ahead of the Independence Day holiday, and again the following year.

Both incidents left dozens of injured, but no fatalities.
