Kenyan police have fired tear gas and water cannons to disperse protesters as thousands took to the streets to mark the first anniversary of anti-government demonstrations that left dozens dead.

The government regulator, the Communications Authority of Kenya, has ordered all television and radio stations in the country to stop broadcasting live coverage of protests of the youth-led march, which began Wednesday.

The government agency falsely claimed live coverage of the demonstrations violated Kenyan laws, while threatening regulatory action for non-compliance with the directive. Many of the stations did not immediately cease broadcasting, including CNN affiliate Citizen TV.

Thousands of people demonstrated in the capital of Nairobi, the coastal city of Mombasa and other towns to mark the protest anniversary.

In Nairobi, roads leading to the Kenyan Parliament building and the president’s office were barricaded ahead of the demonstrations.
