The Colombian government has frozen peace talks with the ELN rebel group following a series of bombings. The attacks, only one of which was claimed by ELN, killed several police officers and injured dozens of others.
An upcoming round of peace negotiations between the Colombian government and the National Liberation Army (ELN) was suspended by the country's president on Monday following a weekend of deadly attacks.
The developments are a step back in efforts to end Colombia's 50 years of conflict, which appeared to be nearing a resolution.
Two sides at odds Colombian PresidentJuan Manuel Santos announced the decision to freeze the talks at an event near Bogota, saying that his "patience and the patience of the Colombian people has its limits."
He said the talks would remain suspended "until we see coherence between the ELN's words and its actions."
The ELN said in a statement on Monday that it would back a new ceasefire but that its attacks would continue if there was no ceasefire deal in place.
A step back from peace: The ELN entered into peace talks with the Colombian government in February 2017, but the negotiations have made halting progress due to ongoing attacks.
FARC deal: Santos won a Nobel Peace Prize in 2016 for securing a peace deal with a larger rebel group called the Revolutionary Armed Forces of Colombia (FARC). Following its disarmament, the group formed a political party called the Revolutionary Alternative Common Force.
Who are the ELN: The rebel group was founded by radical Roman Catholic priests in 1964 and currently has around 2,000 members. They are considered more radical than FARC and less centralized.
