Colombia has suspended peace talks with the National Liberation Army, or ELN, for second time in less than a year after blaming the rebel group for violence that has been affecting a northeastern region of the country in recent days.

A fresh outbreak of guerrilla violence amid a faltering peace process in Colombia has left more than 80 people dead, including civilians, and displaced around 11,000 in just four days,

More than 80 people were killed in the country’s northeast over the weekend following the government’s failed attempts to hold peace talks with the National Liberation Army, a Colombian official said.
