Authorities in Greece warn the dust concentrations can reduce sunlight and visibility, while increasing levels of fine pollution particles pose health risks
Clouds of dust blown in from the Sahara covered Athens and other Greek cities on Tuesday, one of the worst such episodes to hit the country since 2018, officials said.
A yellow-orange haze smothered several regions after days of strong winds from the south, limiting visibility and prompting warnings from the authorities of breathing risks.
