Washington, Jul 30 (IANS): US President Joe Biden declared that "a major disaster exists" in Kentucky amid the deadly flooding triggered by torrential rain in the state, according to the White House.

Biden has ordered federal aid to supplement Kentucky and local recovery efforts in the areas affected by severe storms, flooding, landslides, and mudslides, Xinhua news agency quoted the White House as saying later Friday.

"Damage assessments are continuing in other areas, and more counties and additional forms of assistance may be designated after the assessments are fully completed," it added.

In response, Kentucky Governor Andy Beshear tweeted that the federal funding "is critical for our recovery efforts and Kentuckians impacted by the historic flooding."

He also confirmed that at least 16 people have died, while "the flooding situation in Eastern Kentucky is ongoing".

The Governor further said he expected the number to more than double, and "it's going to include some children", while there were also a number of people unaccounted for.

Besides Kentucky, floods have also hit parts of West Virginia and Virginia.

West Virginia Governor Jim Justice declared a state of emergency for six counties.
