A lightning bolt in the United States stretched almost 500 miles across three states - setting a record for the longest flash.
The single flash extended 477.2 miles across Texas, Louisiana and Mississippi in April 2020, the World Meteorological Organisation (WMO) said. That beat the old record of 440.6 miles set in 2018.
Also in 2020, a single lightning flash over Uruguay and northern Argentina lasted 17.1 seconds, nipping the old record time of 16.7 seconds.
