Huge amounts of Saharan dust have engulfed Greece, making it look more like Mars than a part of the Meditteranean.
In Athens people gawped at the dust-streaked Acropolis.
Many residents have been wearing masks to protect themselves.
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.
Weather reports suggest more thick Saharan dust will arrive on Sunday.
By then some of it will have travelled to Israel, Lebanon, Jordan and Syria.
And the dust will also reach the Balkans, most of the Adriatic sea and southern Italy.
