An international media rights group says Burma's military government has been harassing journalists since anti-government demonstrations in September.

Reporters Without Borders said Wednesday police continue to search for journalists and activists who photographed and filmed the crackdown on the demonstrations led by Buddhist monks.

It says at least nine journalists have fled to Thailand, and at least three others have been arrested and are still being held.

The group said that while privately-owned media in Burma has resumed publishing, the country's Censorship Board has stepped up its controls. It also says the government is strictly controlling the sales of foreign publications and that surveillance at Internet cafes has increased.

The Burmese government detained thousands of protesters during the September pro-democracy demonstrations.  Burma says 15 people died in the protests but the United Nations puts the figure at 31.
