Colombia's ELN rebels likely behind Bogota blasts - president

BOGOTA (Reuters) - Two bomb blasts in Colombia's capital Bogota on Thursday were likely the work of the smaller of the country's two leftist rebel groups, the National Liberation Army or ELN, President Juan Manuel Santos said.

The bombs were detonated in front of two offices of the Porvenir pension fund, a subsidiary of the Grupo Aval [GRPAV.UL] financial conglomerate, injuring seven people. The government pledged to provide a heavier army and police presence in Bogota.
