Kenyan police ban a planned march in Nairobi to mark the annual Saba Saba Day protest anniversary. Authorities announce that the march will not be allowed, citing security concerns. Police also plan heavy deployments across the city, which they say will affect movement and disrupt traffic on Tuesday. The decision is presented as a public-safety measure ahead of the anniversary event that typically draws demonstrations. While the outlets report the police directive to stop the march, they also indicate that the protest anniversary is part of an annual cycle of commemorations. The coverage from both sources focuses on the same official action by police and the expected impact on local traffic due to increased security presence. No alternative route, date, or approved form of demonstration is mentioned in the reports provided. The ban therefore centers on preventing the specific planned march in Nairobi during the protest anniversary period.
