Four of the Arkansas fatalities were reported in Wynne, about 100 miles (160 km) east of Little Rock, Cross County Coroner Eli Long said.
One person was killed and more than 50 people were hospitalized in North Little Rock, Pulaski County spokeswoman Madeline Roberts told the Washington Post.

Biden also reached out to Illinois Governor J.B. Pritzker, the White House added.

Concertgoer Gabrielle Lewellyn told WTVO television that people took refuge in the basement when the roof came crashing down.
