More than 35 people called police on Wednesday night to report seeing UFOs during heavy snow.

The callers, including a traffic cop, said 50 orange lights hovered in the sky for 15 minutes before drifting into the night.

Moira Dawson, 57, said: "We thought they were fireworks but they didn't make any noise. They just floated in the snowfall."

Another witness near Gatwick airport in West Sussex said: "We thought it was an invasion."
