An international media organization is calling on Myanmar to investigate the arrests and alleged police beatings of journalists covering a demonstration against a new education bill.

The reporters got caught in the middle of a violent confrontation between 500 baton-wielding police and 100 demonstrators who were trying to march to the country's biggest city of Yangon last week.

Witnesses said police turned on the journalists, clubbing several and detaining two.

The International Press Institute's Barbara Trionfi on Tuesday asked the government to investigate.

The Vienna-based organization will host its annual World Congress and General Assembly this month in Myanmar — a country that recently started moving from dictatorship to democracy.
