On September 10, 2026, a fresh territorial confrontation erupted along the Sarstoon River between Belizean civilian activists and Guatemalan military forces, reigniting long-simmering tensions over the undelimited border between the two Central American nations. Belize’s Minister of Foreign Affairs Francis Fonseca addressed the public the following day, framing the incident as just the latest in a series of recurring disputes that will persist until the International Court of Justice (ICJ) issues a binding final ruling on the contested territorial claim.
According to Fonseca, the confrontation unfolded when 14 armed Guatemalan naval vessels blocked the Belize Territorial Volunteers (BTV), a grassroots civic group that carries out an annual expedition to Sarstoon Island to affirm Belize’s territorial sovereignty. The foreign minister noted that the scale of Guatemalan military presence in the area was far heavier than what is typically observed in the region, indicating a deliberate, coordinated show of force.
Despite the tense standoff, Fonseca highlighted a positive outcome from the incident: no injuries or violent clashes occurred between the opposing parties. The Belize Defence Force (BDF) and Belizean Coast Guard were still able to conduct a planned flag-raising ceremony at the country’s Forward Operating Base along the border, with members of the BTV in attendance to participate in the event.
Fonseca reaffirmed that bilateral diplomatic engagement between Belize and Guatemala remains active, including ongoing direct dialogue between Belizean Prime Minister John Briceño and Guatemalan President Bernardo Arévalo to manage escalating tensions. In line with standard protocol following such border incidents, Fonseca confirmed that Belize has formally documented the Guatemalan military’s incursion and submitted an official diplomatic note to Guatemala, registering Belize’s clear objection to the actions of the Guatemalan Armed Forces (GAF).
The foreign minister also addressed growing public calls to revoke Belizean fishing licenses held by Guatemalan fishermen who hold permanent residency in Belize, after several of these fishermen were reported to have participated in Thursday’s confrontation. Fonseca explained that a full military investigation into the incident is nearly complete, and its findings will be reviewed by Belize’s National Security Council—an agency that holds legal authority to revoke the licenses if violations of Belizean law are confirmed. “If they have violated any of our laws, we will certainly take action,” Fonseca emphasized.
To date, the ICJ has not scheduled oral arguments for the territorial dispute case, nor has it set a timeline for releasing its final binding ruling. Until that decision is delivered, Fonseca made clear that similar border confrontations can be expected to continue along the disputed Sarstoon River region.
