Australia’s biggest city, Sydney, has been hit by the worst dust storm in decades.
Even its iconic Opera House was obscured by the fine red dust, carried for miles across eastern Australia by gale-force winds.
Residents awoke to a strange orange glow, fearing bush fires or a nuclear explosion.
While many people chose to stay at home, others continued with their morning commute.
Motorists were warned to drive carefully as visibility was severely reduced.
In several areas, the sky took on a crimson hue.
Even the sea was transformed, as seen in this picture from Sydney resident Gareth Bishop.
Everything in the city was covered in dust.
Conditions began to improve around midday, and residents said blue skies were back in the evening.
What are these?
