At least 2,290 livestock are dead with many others facing starvation after a blizzard brought heavy snow to a county in north China's Inner Mongolia Autonomous Region on Wednesday night.

Roads to Wulate Back Banner bordering the Republic of Mongolia are still blocked by one-meter deep snow, according to the county government.

Wednesday's blizzard was the worst of seven snow storms to have hit the county since November. It has blocked all major roads in pastural county, said a spokesman with the county government Thurday.

He said the livestock mainly died of starvation, as the snow stopped them from gazing and the county did not have enough stored winter feed.

"The county is currently short of 21.5 million kg of hay and other stored winter feed," he said.

He said road transport to five worst hit townships in the county were blocked, affecting 4,928 people and 248,000 livestock in the area.
