At least 80 people have been killed and thousands displaced in north-east Colombia after the collapse of a fragile truce between rebel groups vying for control of the one of the country’s largest cocaine hubs. Violence between the National Liberation Army (ELN) and dissident factions of the Revolutionary Armed Forces of Colombia (Farc) has rapidly escalated in the lawless region bordering Venezuela since Thursday, forcing at least 5,000 people to flee their homes. School has been suspended indefinitely as classrooms have been converted into emergency shelters for families fleeing their homes and the region has requested emergency humanitarian assistance, said
