Rebel groups launched a wave of coordinated attacks on civilian and military targets in Colombia leading up to the May 2026 presidential election [1].

The surge in violence threatens the stability of the democratic process during a critical transition period. These attacks target the state's ability to maintain order and security as the country prepares to choose its next leader.

Reports indicate a series of strikes across the country, with significant concentration in southwest regions including Nariño and Cauca [2]. While some reports describe the scale as dozens of attacks [2], other sources specify that 26 coordinated terrorist attacks occurred over a single weekend [1].

President Gustavo Petro said the violence is a calculated political move. "These attacks are an effort to undermine my party’s candidate and destabilize the country ahead of the election," Petro said [3].

The National Liberation Army (ELN) and other rebel factions have been identified as participants in the unrest [1]. The coordination of the strikes suggests a strategic effort to project power and disrupt government operations in rural and urban hubs.

Lilia Luciano of CBS News said that 26 coordinated terrorist attacks were reported on civilian and military bases in Colombia over the weekend [1]. The timing of these incidents coincides with the period in which Colombians are electing a new congress, and selecting presidential candidates [4].

Security forces remain on high alert in the southwest regions to prevent further escalations. The government continues to monitor the movement of rebel groups as the May 2026 vote approaches [4].

Twenty-six coordinated terrorist attacks were reported on civilian and military bases in Colombia over the weekend.

The escalation of violence by groups like the ELN indicates a strategic attempt to influence the outcome of the May 2026 election by creating a security vacuum. By targeting both military and civilian infrastructure, these groups seek to challenge the legitimacy of President Petro's administration and pressure the government into concessions or political instability before the vote.
