The town of Ain Sefra, on the edge of the Sahara desert, was hit by icy weather last week and even snow.
Snowfall is very rare in the Sahara, despite the fact that it can be cold at night because there's rarely enough water around for any kind of precipitation.
The Sahara is the hottest desert on the planet.In the town of Ain Sefra, Algeria, residents woke up to find snow.
The desert heat falls away at night and can drop to freezing, but having enough water in the air for snowfall is a rare sight.
In 2016, Nasa published satellite images of snow near the town, the first recorded snow in the area in almost 40 years.
The snow vanishes once the day heats up.
