Despite the severity of the incident, Colombia and Peru have indicated a willingness to address it through diplomacy

 An incident on April 12, 2026, has reignited diplomatic and security tensions in the Amazon border region between Colombia and Peru, following an exchange of gunfire between a Colombian civilian vessel and the Marina de Guerra del Perú, a Peruvian Navy River unit, on the Putumayo River. The incident left one Colombian citizen dead and one person injured on each side.

The episode occurred near Marandúa (Amazonas, Colombia), across from the Peruvian town of El Estrecho. According to Colombia’s Defense Minister, Pedro Sánchez, the fatal victim was identified “as José Miguel Gutiérrez Baquero, owner of the cargo vessel involved in the incident, and one of his sons was injured,” while two other crew members were detained by Peruvian authorities.

Conflicting accounts of the operation

According to the Peruvian government statement, “the incident occurred during a patrol operation aimed at securing the electoral process,” previously coordinated between the two countries. Authorities said two Navy speedboats requested that the Colombian vessel stop for identification.

Peru’s Ministry of Foreign Affairs, which is leading the process, said that “the Colombian vessel refused to comply with the control order and opened fire on two Peruvian Navy units, which returned fire.” As a result, “a member of the Peruvian Navy was also injured, although he is out of danger.”

Colombian authorities, led by the Foreign Ministry, have requested a full clarification of the events and verification of the circumstances surrounding the exchange of gunfire.

Diplomatic channels activated

Following the incident, the governments of Colombia and Peru activated diplomatic and military channels. Colombia’s defense minister said that “preliminary measures were agreed, including prioritizing medical attention for the injured, facilitating the work of judicial authorities, and establishing a binational commission to investigate what happened.”

Colombia’s Foreign Ministry formally requested clarification of “the circumstances of time, mode and place” of the attack, while the Peruvian government expressed its “willingness to cooperate and maintain border coordination mechanisms.”

The detained individuals “remain in the custody of the Fiscalía Provincial Mixta de Putumayo, with access to consular assistance and due process guarantees.”

So far, no final responsibilities have been determined, and both countries agree on the need for a thorough investigation. Both governments said the issue will be addressed at the next High-Level Mechanism on Security and Judicial Cooperation meeting, scheduled for May 2026 in Bogotá.

Context of prior tensions

The incident comes amid sensitive bilateral relations. In recent months, Colombia and Peru have had disagreements over territorial issues in the Amazon, particularly regarding Santa Rosa de Loreto island.

The dispute dates back to August 5, 2025, when President Gustavo Petro said on X that the “government of Peru has taken over territory that belongs to Colombia” and alleged a “violation of the Rio de Janeiro Protocol, which defines the boundaries between the two countries.”

“The Rio de Janeiro Protocol established that the border is the deepest channel of the Amazon River and that any dispute must be resolved between the parties,” Petro said, referring to the emergence of new river islands “north of the current deepest channel,” which, according to his position, should belong to Colombia.

In response, Peru’s Foreign Ministry expressed its “strongest and most forceful protest,” stating that the island, home to about 3,000 residents, mostly Peruvians, is part of its territory and is key to regional river trade.

Tensions escalated days later when then-presidential pre-candidate Daniel Quintero traveled to the island and raised a Colombian flag during a campaign event broadcast on social media, saying: “I will not allow them to take the Amazon from us. Santa Rosa is Colombia.”

The Peruvian government described the act as an “unnecessary action” that “distracts from the cooperation efforts that Peru and Colombia must prioritize to jointly address urgent challenges.”

Colombia’s Defense Ministry detailed a plan to bolster security along the Ecuador border

Colombia’s government has announced a package of measures to strengthen security in municipalities along the border with Ecuador, amid escalating tensions between the two countries over security and trade issues.

According to a statement released by the presidency, the actions include “the deployment of 200 additional National Police officers and 270 soldiers, as well as enhanced maritime and riverine capabilities for territorial control and the fight against drug trafficking.”

The plan also includes technical support for surveillance systems, the deployment of two armored platoons to ensure troop mobility, and meetings aimed at strengthening joint operations by security forces and control at border crossings.

Defense Minister Pedro Sánchez announced the measures, stating that “we will not allow criminal groups seeking to profit from illegal activities such as drug trafficking, illegal mining, extortion and smuggling to affect security indicators.”

He added that security forces have already seized 2.4 tons of drugs and remain deployed in the region “to protect our seas and critically disrupt drug trafficking.”

Context: security and trade tensions

The measures come days before Ecuador’s tariff increase takes effect, raising the so-called “security tariff” on Colombian goods from 50% to 100% starting May 1, 2026.

Ecuadorian President Daniel Noboa told Revista Semana magazine that the decision is not part of a “trade war” with Colombia but rather reflects the costs of reinforcing border security. “We have to spend twice as much, and it costs $400 million USD more per year to keep our armed forces deployed at the border,” he said.

For its part, Colombia’s government has rejected claims of insufficient action on border security. Minister of Commerce, Industry and Tourism Diana Marcela Morales Rojas said Colombia has kept diplomatic channels open.

“We have exhausted all diplomatic efforts and maintained open dialogue channels with the Government of Ecuador, seeking a solution that benefits both countries, businesses and, above all, communities on both sides of the border. However, we have not received a positive response,” she said in a statement.

At the same time, Colombia is evaluating its tariff response. Although President Gustavo Petro previously said he would not impose 100% tariffs on Ecuador, a draft update to Decree 170 of 2026 has recently emerged proposing differentiated tariffs of 35%, 50% and 75% on imports from the neighboring country. So far, the proposal has not been signed or officially published.
