Huge amounts of Saharan dust that have engulfed Greece, reached Russia's Kuban, according to witnesses.
Many residents of Crete have been wearing masks to protect themselves, Euronews reported.
Weather reports suggest Saharan dust will have travelled to Israel, Lebanon, Jordan and Syria, as well as the Balkans, most of the Adriatic sea and southern Italy.
North Africa is just a few hundred kilometres south of the Greek island of Crete and it was particularly hit. Current strong southerly winds mean the dust has easily crossed the Mediterranean Sea.
