The violence broke out Tuesday when opposition political parties accused the ruling Mongolian People's Revolutionary Party of vote-rigging in parliamentary elections held last Sunday, Xinhua, the state-run Chinese news agency, reported. A four-day state of emergency was called when the protests turned violent.

Many of the demonstrators were supporters of the Democratic Party, which has now agreed to allow its members to be criminally charged in the rioting in exchange for gaining access to ballot recounts in some disputed districts, Xinhua said.

Five people reportedly were killed and more than 300 others injured in the Mongolian riots. President Nambariin Enkhbayar declared the country's first-ever state of emergency in the capital area Wednesday, the news agency said.
