Blizzards are battering parts of Eastern Europe, forcing roads to close, trains and flights to be cancelled and producing power outages.

The snow was blanketing parts of Romania, Serbia, the Czech Republic and Poland.

Romania's transportation ministry said 12 major roads were closed Sunday due to heavy snow and three Black Sea ports had to shut down because of high winds. Railway authorities said 20 trains had been canceled. At least three flights were also canceled.

The Interior Ministry said 6,000 officers were helping to clear the snow.

Some 14 communities in Romania suffered power outages and the Education Ministry said schools would close Monday in Bucharest, the capital, and in other southeastern regions.

The cold snap also gripped other countries, causing traffic problems and power outages.
