Egypt's rare storm triggered a flash flood that killed at least three people and hordes of scorpions rushed into people's homes.
Last weekend, more than 500 people in the southern Egyptian city of Aswan were stung by scorpions fleeing thunderstorms and torrential rains.
Egypt's state-run Ahram newspaper said injured Aswan residents were transferred to hospitals for anti-venom injections.
The Aswan region typically receives around 1 mm of rain each year, making Friday's heavy thunderstorms and hailstorms a rare event. The Egyptian fat-tailed scorpion, which usually inhabits the desert, is one of the deadliest scorpions in the world. If left untreated, people can die within an hour of being stung.
According to Ashraf Attia, the governor of Aswan, three members of Egypt's security forces were killed in a flash flood, the worst in 11 years.
Torrential rains in the Aswan Desert destroyed homes and damaged roads and trees.
