Amid more than 20 tornadoes that caused devastation across central and southern states, one may be the longest in US history
Rescuers worked into the night searching for survivors after what could be the longest tornado in US history left a trail of destruction from Arkansas to Kentucky, part of a vast stormfront that is believed to have killed up to 100 people.
Kentucky governor Andy Beshear said the path of devastation was about 227 miles (365km) long, which, if confirmed, would surpass the 218-mile Tri-State tornado in 1925, which killed at least 695 people and destroyed 15,000 homes across Missouri, Illinois and Indiana.
