On 13 January, a night guard at the museum of Zavkhan province was murdered by two criminals who stole some of the most valuable objects of museum's collections such as khalkha woman's hairdresses, belts and rare coral mask of Jamsran. They even set the museum on fire to erase any possible traces. But province's fire station and people extinguished fire promptly.
