Colombia's armed forces have resumed military operations against the ELN rebels after the ceasefire agreement expired on Saturday.
The government and the ELN have been in peace talks, but the ceasefire was not renewed despite those negotiations.
The ELN claims the government has not fulfilled its commitments during the peace talks, and they are demanding to be removed from the list of armed groups before considering a new ceasefire.
The ELN is a rebel group that has been fighting the Colombian government for many years, and they represent a significant challenge to the ongoing peace process.
