FLASH floods that tore through several towns in southwest France following an overnight storm killed at least 12 people, authorities said Monday.

Some residents had to be helicoptered from rooftops as the equivalent of several months of rain poured down in a few hours and turned waterways into raging torrents.

Initially, the French Interior Ministry reported 13 deaths from the floods in the Aude region. French officials lowered the number to 10 later, saying some victims had been counted twice.

The Interior Ministry and Aude officials put it at 12 after two more bodies were recovered in the towns of Trebes and Carcassonne.

The River Aude that flows through towns such as Carcassonne and Trebes was among the waterways that overflowed from the exceptional rainfall, and the flooding was the region’s worst in more than a century, the French agency that monitors flood risks said.
