Colombia invites dialogue with ELN rebels

Colombian President Juan Manuel Santos says his government is ready to start peace talks with the country's second-largest left-wing rebel group, the National Liberation Army (ELN).

The announcement comes a day after the ELN released a Canadian hostage it had been holding for months, Gernot Wober.

Meanwhile, a Colombian court has rejected appeals against a law facilitating talks with rebel groups.

Colombia has already opened talks with the largest rebel group, the Farc.
