France Tactical: UNOC summit to take place in Nice on June 9-13; maintain heightened vigilance

Jun 2025

8:23 UTC

Current Situation

Between June 9–13, the third United Nations Ocean Conference (UNOC) will be held at Port Lympia in Nice, Alpes-Maritimes department.
World leaders, scientists, and environmental groups will attend to discuss initiatives aimed at protecting marine life. Approximately 15,000 participants are expected to participate. The conference is intended to conclude with the adoption of a non-binding political declaration outlining concrete commitments by states to safeguard the oceans.
A Securite Interieure et Lutte Contre le Terrorisme (SILT) perimeter system has been put in place at the Port of Lympia and will remain in effect until June 14. Associated events will be held at several venues across Nice, including the Mediterranean University Center, the Palais des Expositions, and the Palais Sarde, where SILT perimeters are also active.
All security, access measures, and traffic restrictions can be found here (in French).
Additionally, June 8 will be marked by World Oceans Day celebrations, with festivities planned throughout the city.

Assessments & Forecast

Given the high-profile nature of the summit and the extensive security measures in place, significant disruptions to pedestrian and vehicular movement are expected across central Nice from June 9–13. Disruptions will be particularly severe in the vicinity of Port Lympia and adjacent areas where security perimeters and traffic diversions have been established. Public transport services near summit venues—including bus and rail—are also expected to face disruptions. Travelers are advised to monitor updates here (in French).
As public transport availability diminishes, a larger number of commuters are likely to turn to private vehicles and taxis, which will further aggravate traffic congestion across central Nice. This is expected to lead to delays on key thoroughfares, including major ring roads and access routes to summit locations.
While no protests have been announced as of writing, the summit is likely to attract demonstrations by pro-climate and far-left activist groups. Based on precedent and the tendency of such groups to engage in disruptive tactics—including sit-ins, road blockades, and acts of vandalism such as throwing paint at buildings—there remains a latent risk of unrest, including localized clashes between demonstrators and police.
Additionally, the threat of sabotage or arson attacks aimed at disrupting the UNOC summit remains credible. The prefect of Alpes-Maritimes has publicly stated that the risk of attacks targeting the electricity grid during the summit has been “reassessed.” This follows a series of sabotage and arson attacks targeting electrical infrastructure during high-profile events, including the Cannes Film Festival on May 24. In the event of such incidents, operational disruption, including power outages, transport delays, and communication network failures, is likely. Such failures, particularly power outages, have the potential to significantly impact critical infrastructure, including hospitals, emergency services, and traffic control systems.

Recommendations

Those operating or residing in Nice on June 9-13 are advised to maintain heightened vigilance in the vicinity of the aforementioned locations due to the associated risks at the UNOC summit discussed above.
Remain cognizant of authorities’ updates regarding security measures, including the SILT system that has been put in place.
Maintain heightened vigilance in the vicinity of any protests related to the UNOC summit in Nice on June 9-13 due to the latent risk for unrest
Allot for disruptions to travel in Nice due to road closures and expected public transport disruptions
