On Thursday, hundreds of Mongolian civil rights activists gathered in Ulan Bator's central square to demand the resignation of the country’s health minister. The health minister is blamed for not doing enough to control the spread of the H1N1 virus, also known as swine flu.

Mongolians were shaken by the late but sudden onset of H1N1 in October of last year, before the country had procured supplies of vaccine.

About 30 Mongolians have died from the flu strain so far, while the country's first donated vaccine shipment from the World Health Organization only arrived in January.

Protesters warned of further unrest if the government did not meet their demands by next month.

The protest ended peacefully. It is the first demonstration in the heart of the capital since post-election riots in July 2008.
