Iran Press/ America: A three-week-long heat wave this month strained the energy grid with record demand, forced authorities to suspend classes in some areas and left many Mexicans sweltering.
Over two-thirds of the deaths came the week of June 18-24, with the remainder the previous week, the ministry said in a report on extreme temperatures.
During the same period last year just one heat-related fatality was registered. Nearly all the deaths were attributed to heat stroke, with a handful from dehydration.
Around 64 percent of the deaths occurred in northern state of Nuevo Leon bordering Texas. Most of the rest were in neighboring Tamaulipas and Veracruz on the Gulf coast.
