Hundreds of people wearing all-black balaclavas have caused traffic to come to a standstill in Dover, England, as part of a protest. The demonstration took place near the Port of Dover on Saturday morning, with reports indicating that around 300 individuals were involved. Kent Police confirmed they are aware of the protest and are working on-site to engage with the demonstrators. Social media videos show large groups of people walking along major roads and across roundabouts, blocking traffic on the A20, a key route in and out of the port. The protest is believed to be related to opposition to migrants crossing the English Channel in small boats, a controversial issue in recent years. Reform UK councillor John Baker, representing Kent County Council, suggested the demonstration was a "stop the boats" protest, a term used to describe efforts to reduce the number of migrants arriving in the UK by sea. The Port of Dover has reported that all routes into and out of the town and port are affected, with traffic coming to a complete halt. P&O Ferries issued a travel update, stating that access to the port is currently restricted and that passengers missing their sailing would be accommodated on the next available one. Local authorities and officials have responded to the demonstration with mixed reactions. A local councillor mentioned that some women in the area had felt frightened by the large group of protesters. Meanwhile, Dover and Deal MP Mike Tapp criticized the demonstrators, calling them "idiots." Kent Police emphasized that they are on the scene and are engaging with the protesters as they manage the situation. The protest has highlighted the ongoing tensions surrounding migration and border control in the region. The demonstration has underscored the impact of such protests on local communities and infrastructure. While the police have not indicated any arrests or significant disruptions beyond the traffic, the event has drawn attention to the broader debate over immigration policy and public safety. As the situation develops, officials continue to monitor the situation and work to ensure the safety of residents and travelers in the area.
