Fresh warnings for ice have been issued for parts of Scotland as the cold snap continues to make conditions tricky for drivers and pedestrians.

The Met Office's yellow "be aware" warning covers much of Scotland, from 6pm on Saturday until 10.30am on Sunday.

It comes after people woke up to a widespread frost on Saturday morning.

And police and health officials have warned that recent adverse weather conditions had led to a number of road collisions and a spike in the number of injuries caused by people slipping and falling.

The new warning from the Met Office states: "Icy patches will be a hazard on some untreated roads, pavements and cycle paths. Some injuries are possible from slips and falls on icy surfaces."

The Met Office's chief forecaster wrote: "Any showers will die out during Saturday evening, with temperatures falling below freezing across much of the area, allowing a frost and some icy patches to develop.

"Outbreaks of rain will spread eastwards later in the night and during Sunday morning, with some of this rain possibly falling on to surfaces that will still be below freezing, thus increasing the risk of ice for a few hours."
