A car bomb has exploded in southern Colombia, killing at least two people and injuring several others.

Police said the bomb went off early on Friday morning outside a hotel in the town of Puerto Asis, near Colombia's border with Ecuador.

The authorities are blaming the attack on guerrillas from the Revolutionary Armed Forces of Colombia, the FARC, who've been fighting right-wing paramilitary groups for control of the region.

In December, a car bomb in the same region killed five people.
