Greek Prime Minister Kyriakos Mitsotakis has apologised to drivers who were stranded on Greek roads due to heavy snowfall.
Mitsotakis offered a “personal and sincere apology” during a cabinet meeting on Wednesday, but blamed private road operators for mishandling the reaction to the storm.
"There were mistakes and shortcomings which have to be fixed," he added.

Vassilis Halkias, the CEO of the private company managing the Attiki Odos ring road, resigned on Tuesday evening. The company had earlier announced that they would award €2,000 in damages to drivers who were left stranded on the toll road.
Heavy snowfall has caused major disruptions in Greece and neighbouring Turkey, halting flights, blocking highways, and causing power outages.
Thousands of drivers were left trapped on major roads in the Greek capital for hours, with many forced to spend the night in their cars in freezing temperatures.

Outrage against the Greek government has been growing, with several national newspapers declaring the snowstorm a "fiasco".
Other Greek social media users criticised the authorities for a lack of snowploughs and snow-clearing equipment.
Civil Protection Minister Christos Stylianides -- who was only appointed after last year's devastating wildfires -- has also apologised but blamed the crisis on the Attiki Odos company.
In neighbouring Turkey, life was slowly returning to normal on Wednesday after the heavy snowfall.
Authorities at Istanbul's international airport announced that they had reopened two of their three runways, with the third due to resume traffic later in the day.
