Deadliest indirect lightning strike: Dronka, Egypt on November 2, 1994, when 469 people were killed by a lightning-caused oil fire.

In 1994, a flash of lightning caused a fire that ignited three oil tanks, each holding about 5,000 tons of aircraft or diesel fuel. The railway line holding the tanks collapsed in a flood and floodwaters carried the blazing fuel into Dronka.
