Colombia and Ecuador agreed to open a joint investigation to clarify how a bomb of Ecuadorian origin ended up on Colombian territory, in an episode that has heightened diplomatic tensions between the two countries.
The announcement comes after several days of mutual accusations and after Colombian President Gustavo Petro publicly denounced that his country was being bombed from the neighboring country.
The discovery of the explosive device in the border area, which did not detonate and was later destroyed in a controlled manner, set off alarms in Bogota and Quito. Although both sides have insisted that there was no intention to attack Colombian territory, the incident forced the activation of diplomatic channels and cooperation mechanisms to prevent a further escalation.
The Colombian complaint goes far beyond the device that was found, as President Petro recently stated that there would be a total of 27 burned human bodies as a result of alleged Ecuadorian bombs that had fallen on the Colombian side of the border during the Ecuadorian army’s fight against drug trafficking groups.
Colombia and Ecuador launch investigation into how a bomb reached the border
The agreement between Colombia and Ecuador includes sending a binational technical commission to the border area in the coming days. The objective is to determine the exact circumstances under which the bomb crossed into Colombian territory and to establish responsibilities, if any.
As explained by Colombian Defense Minister Pedro Sanchez, the decision responds to the need to clarify “how and why it arrived” in the country, after it was confirmed that it belongs to the arsenal of the Ecuadorian Armed Forces.
Ecuadorian authorities, for their part, have maintained that the military operation in which the bomb was used took place within their own territory, specifically in the province of Sucumbíos. They have also reiterated that there was no intention to affect Colombia, in an attempt to contain the political impact of the episode.
During the virtual meeting held last Wednesday, participants included Ecuador’s Defense Minister Gian Carlo Loffredo; the head of the Joint Command of the Ecuadorian Armed Forces, Henry Delgado; along with Minister Sánchez and Colombian military authorities.
After the meeting, Colombia’s top defense official stated on his X account that “the meeting was productive, respectful, and frank. Ecuador reiterated that there was no intention whatsoever to affect Colombian territory.”
The case has highlighted the risks associated with military operations in border areas, where geography and proximity between countries can lead to cross-border incidents even without direct intent.
Confirmed facts and hypotheses about the bomb
In the same social media post, Minister Pedro Sanchez added a summary of the facts confirmed so far, which began on March 3, when Ecuador’s Armed Forces carried out a military operation that included a bombing at a location known as La Isla, in Sucumbios (Ecuador), just meters from the border with Colombia.
According to Sanchez, “the device found in Colombian territory corresponds to one of the bombs used by Ecuador in that operation.” In addition, the minister stated that “the initial point of impact of the bomb was in Ecuadorian territory, where a fuse from the same device was also found,” but that the device did not explode.
Finally, this week, more specifically on Monday, March 16, “the discovery of the bomb in Colombian territory became publicly known.”
After expressing the concerns of the Colombian government over this unusual situation, the defense minister explained the two hypotheses being considered to explain how the bomb reached Colombian territory. On the one hand, it is speculated that the bomb may have “bounced and unintentionally reached Colombian territory,” and on the other, it is also possible that “the bomb was later moved by third parties from the point of impact to Colombian territory.”

Petro’s allegations and Ecuador’s response
The investigation comes after President Gustavo Petro claimed that Colombia was being bombed from Ecuador. The president asserted that the explosive device found could not be attributed to illegal armed groups, noting that they do not have the aerial capability to carry out such attacks.
Petro also linked the discovery to a series of explosions that occurred in the border area and mentioned the appearance of dozens of charred bodies, which heightened the seriousness of his statements and sparked international concern.
“The bombings along the Colombia-Ecuador border do not appear to be the work of armed groups—they don’t have aircraft—nor of the Colombian security forces. I did not give that order. There are 27 charred bodies, and the explanation is not credible. The bombs are on the ground near families, many of whom have peacefully decided to replace their coca leaf crops with legal crops,” the Colombian president stated in a comment posted on his social media account X.
From Quito, President Daniel Noboa categorically rejected the accusations and maintained that his country’s military operations have been carried out exclusively within its own territory. The Ecuadorian government insisted that its actions are aimed at drug trafficking networks and not at Colombia.
This exchange of accounts marked a new episode in the diplomatic crisis that the two countries have been experiencing since January, while also being engaged in a tariff dispute stemming from disagreements over how to confront illegal armed groups operating on both sides of the border.
The border region between Colombia and Ecuador has historically been a strategic corridor for drug trafficking and the presence of illegal armed groups. The combination of jungle terrain, difficult access, and weak state presence has facilitated the operations of criminal networks acting on both sides of the border.
In this context, military operations are often conducted under complex conditions, where miscalculations or technical failures can have international consequences. Preliminary investigations suggest that the bomb may have crossed the border after being dropped in Ecuadorian territory during an operation against criminal structures.
Se ha comprobado que la bomba en territorio colombiano es del ejército ecuatoriano.
La investigación continúa y habrá nota de protesta diplomática. https://t.co/pN6OsMmtcm

An attempt to defuse the crisis between Colombia and Ecuador
The creation of the binational commission seeks not only to clarify the facts but also to reduce political tensions between the two countries, at least on this important issue that threatened to result in a potential violation of sovereignty.
However, Ecuador’s Minister of Foreign Affairs, Gabriela Sommerfeld, indicated that her government has not yet received the formal note of protest announced by the Colombian president. Ecuador’s top diplomat insisted that any differences must be resolved exclusively through established diplomatic channels and based on technical information.
In this regard, technical dialogue appears as a way to prevent the incident from escalating into a larger diplomatic crisis or causing irreversible damage to bilateral relations. Both governments have agreed on the need to keep communication channels open and to cooperate on border security issues, despite their differences.
The outcome of the investigation will be key to determining whether the episode was an accident resulting from military operations or whether there were more serious failures in operational protocols. In any case, the incident has already highlighted the fragility of security along the border and how easily an isolated event can escalate at the regional level.
