US President Joe Biden has pledged support to states affected by a swarm of devastating tornadoes that demolished homes, leveled businesses, and left at least 100 people feared dead.

Axar.az reports that describing the tornadoes as likely “one of the largest” storm outbreaks in history, Biden on Saturday approved an emergency disaster declaration for the worst-hit state of Kentucky, where at least 22 people have been confirmed dead.

“It’s a tragedy,” said a shaken Biden. “And we still don’t know how many lives are lost and the full extent of the damage.”

He added, “I promise you, whatever is needed – whatever is needed – the federal government is going to find a way to provide it.”
