Colombia’s second outbreak of guerrilla violence brings death toll to 100

Security forces struggle to tamp down on rising leftwing violence as 11,000 people remain displaced

Colombia's security forces are struggling to contain a surge in leftwing guerrilla violence that has now killed more than 100 people in five days and threatens to derail the country's troubled peace process.

Even as thousands of soldiers rushed to quell violence near the north-eastern border with Venezuela - where more than 80 people have been killed and 11,000 displaced by days of fighting - the defense ministry reported a similar outbreak of fighting in a remote Amazon region.
