ELN rebels kill 9 Colombian soldiers, jeopardizing peace talks.

Nine Colombian soldiers were killed and eight others injured in an attack on an army base in Norte de Santander province by rebels from the National Liberation Army (ELN). The attack is the deadliest since peace talks resumed between the government and the ELN in November. President Gustavo Petro, who aims to bring "total peace" to Colombia, has summoned the government delegation and guarantor countries involved in the peace negotiations for a meeting on Monday to discuss the future of the peace process.
