-36c temperatures across eastern Europe send death toll to 150 - Capital of Italy usually has moderate temperatures but Colosseum is closed over ice fears - Military on alert in the UK as temperatures drop and heavy snow fall is predicted - Over 11,000 villagers in Serbia remain trapped by heavy snow and blizzards - Temperatures across eastern Europe plummet to -30c amid fears of more deaths - Death toll in Ukraine now stands at 101, with 38 people being killed by cold last night
Snow fell in Rome today for the first time in 26 years as freezing temperatures took the death toll across Europe to more than 150. The Italian capital is usually blessed by a moderate climate but the snowfall prompted authorities stop visitors from entering the Colosseum, the Roman Forum and the Palatine Hill, the former home of Rome's ancient emperors.
Snow began falling in the late morning Friday, leaving a light dusting on trees and cars and forming slush on the roads. It wasn't clear if there would be any significant accumulation on the ground.

EU BRACED FOR RUSSIAN GAS SHORTGAE
The European Union is bracing for another potential energy crisis in the dead of winter as Russian gas supplies to some of its member states suddenly have dwindled by up to 30 percent.
The European Commission put its gas coordination committee on alert today, but insisted the situation had not yet reached an emergency level since coordination between nations to help each other had improved and storage facilities had been upgraded.
Commission spokeswoman Marlene Holzner said Russia was going through an extremely cold spell and needed more gas to keep its citizens warm.
She said that Russia's gas contracts 'allow for certain flexibility in case they also need the gas. And that is the situation that Russia is facing at the moment.' The severe winter in Russia has seen temperatures drop to minus 35 C (minus 30 F).
The north of the country has also been gripped by snow and ice that is disrupting train travel.Temperatures plunged as low as minus 22 Celsius (minus 7 Fahrenheit), in Trepalle, a village in the Italian Alps.
Snow in Rome came as the death toll across Europe reached 150. Temperatures have plummeted as low as -36c in parts of Ukraine and Siberia.
In Serbia, at least 11,000 villagers are stranded in their homes by heavy snow and blizzards which have hit remote areas that cannot be reached due to icy, snow-clogged roads.
The worst weather is near Serbia's southwestern town of Sijenica, where it has been freezing cold or snowing for 26 days, and diesel fuel supplies used by snowploughs are running low.
Thirty-eight more people have died overnight as freezing weather grips Ukraine, authorities say. The death toll there from the past week is now 101.
The Emergency Situations Ministry in Ukraine said more than 1,200 other people have been treated in hospital for hypothermia and frostbite as temperatures in some parts of the country sank to -32C (-26F).
Authorities have closed schools and colleges and set up nearly 3,000 heating and food shelters across the country. Health officials instructed hospitals not to discharge homeless patients, even after treatment is finished, to save them from the cold.
Experts said the high death toll reflects the country's inability to deal with the homeless. There have been dozens of death elsewhere in Eastern Europe with thousands of villagers trapped by heavy snow and blizzards in Serbia.
Snow fell across large parts of the UK, with two inches covering Lincolnshire, Norfolk and Suffolk in white, while in the Pennines, fences and phone masts resembled ice sculptures.

The Met Office said up to four inches of snow could fall over the weekend across much of England and Wales, with southern and central areas likely to see the worst of it.
A level three ‘amber’ cold weather alert - the second most serious - was issued, which warns of health risks to the elderly and vulnerable, and the likelihood of disruption to transport.
Level four 4 would mean a 'major cold weather incident', in which normally healthy people are at risk from the cold.
The alerts are tied in to the Government’s Cold Weather Plan and are relayed to organisations such as Age UK, which help the elderly through winter.
The military have been put on alert should conditions deteriorate to a level four.
When freezing conditions struck in 2010, members of the armed forces were called in to help clear snow from the roads and assist residents in particularly hard-hit areas and help clear special locations such as hospitals and care homes.

Newly reported deaths on Thursday because of the cold included 20 in Ukraine, nine in Poland, eight in Romania, and one more each in Serbia and the Czech Republic. Officials said most of victims were homeless.
Polish government spokeswoman Malgorzata Wozniak said her country's victims were mostly homeless people under the influence of alcohol who had sought shelter in unheated buildings.
Officials appealed to the public to quickly help anyone they saw in need.
In Romania, the health ministry on Thursday raised the number of cold-related deaths there to 22.

Dutch authorities banned boats from some of Amsterdam's canals and waterways in the hope the big freeze gripping the city would turn the still water to ice and allow residents to go skating. They also turned off mills and pumps that regulate water levels in the low-lying, flood-prone nation to improve the chances of canals freezing over.
Speed skating is a winter obsession in the Netherlands and hopes are about the possibility of holding the Elfstedentocht - or '11 Town Tour' - skating race being staged for the first time since 1997.
The 200-kilometer (125-mile) tour route takes skaters over frozen canals and lakes linking 11 towns in the northern Netherlands. The tour, which is also a race for elite skaters, has only been staged 15 times since the first official event in 1909.
