Mongolian President Tsakhia Elbegdorj warned Thursday against any violation of laws and regulations as a result of a Doomsday prophecy.

He said on Twitter nothing special would happen on Dec. 21, 2012, the date on the Mayan calendar some claim marks “the end of the world”, and asked Mongolians to trust themselves and science.

Rumor spreads fast and truth lasts for a long time, Elbegdorj said, adding he was not worried about the Doomsday prophecy and would stay at home, at work and in Ulan Bator on Friday.

The Doomsday rumor has spread widely here, with some popular figures calling on people to: “Escape from the capital city and go to countryside. It is far safer in the countryside than urban areas. Save food and candles, fuel and live in traditional Mongolian tents.”

The country’s Buddhist clergy has also warned against accepting the rumor, saying it was baseless and the government should hold those spreading the rumor accountable.
