BOGOTA (Reuters) - Colombia's government has called off peace talks with leftist rebel group the National Liberation Army (ELN), its peace delegation said on Wednesday, following an attack which killed two soldiers and injured more than two dozen.

The decision is another devastating blow to President Gustavo Petro's cornerstone total peace policy, which looked to remove the ELN from its role in the Andean country's six-decades of internal armed conflict.
