Colombia has declared “war” on leftwing guerrillas amid escalating violence that has killed over 100 people and displaced 11,000. President Gustavo Petro, previously focused on negotiations, now adopts a tougher stance against the National Liberation Army (ELN), responsible for deadly attacks. In response, 5,000 troops were deployed to the border area. The violence, involving ELN and Farc splinter groups, has forced residents to flee, with many seeking refuge in Tibú or crossing into Venezuela. The defense ministry reported further clashes in the Amazon, with 20 killed in Guaviare.
