After the series of tornadoes that swept through the southeast and midwestern United States on Saturday night, the search for survivors continues in Kentucky.

As of Wednesday, about 100 residents of the state were reported missing, Governor Andy Beshear announced.

At least 74 people, between the ages of two months and 98 years, were killed when the vortices of air swept more than 300 kilometers through Kentucky at speeds of up to 350 kilometers per hour.

Dawson Springs was almost completely destroyed, as was Mayfield, where at least eight workers died in a candle factory.

The authorities opened an investigation into allegations that management prohibited employees from leaving the factory after the tornado warnings.

In total, the tornadoes tore several thousand houses from the foundations, cut power pylons and uprooted trees.

In Illinois, Missouri, Tennessee and Arkansas, authorities reported a total of about 20 additional fatalities.

Meanwhile, American President Joe Biden declared a disaster for Kentucky to provide federal funds for emergency shelters, reconstruction and loans.
