The demonstration was the latest in a string of rallies since the ruling coalition government collapsed on 13 January following the withdrawal of Mongolia's largest political party, the ex-communist Mongolian People's Revolutionary Party (MPRP).
Participants today called for the dismissal of President Nambaryn Enkhbayar, who belongs to the MPRP.
The MPRP -- which is one seat short of a majority in parliament -- has urged other parties to join it in forming a new government and has nominated its chairman, Mieagombo Enkhbold, as prime minister.
Enkhbayar is scheduled to approve the nominee by 25 January.
