Colombia peace process now at lowest ebb - government

BOGOTA (Reuters) - Colombia's peace negotiations with leftist FARC rebels have hit a critical low as the group steps up violent attacks and the government could walk away from the process unless the group shows more commitment, the government's top negotiator said.

The government has been in Cuba-hosted talks with the Revolutionary Armed Forces of Colombia or FARC since late 2012 to end a 50-year war. Deals have been reached on most of the agenda, but the process is now under unprecedented strain.
