Colombia's second-largest rebel group said it's willing to lay down its weapons if government-brokered peace talks open political space for leftist groups.

The National Liberation Army made the announcement Wednesday by releasing a video of the group's top commander, Nicolas Rodriguez, best known by his alias Gabino, addressing guerrilla fighters at a recent jungle congress. The date of that meeting was not known.

In the video Gabino says the group is willing to enter dialogue with the government aimed at ending the half-century conflict. He didn't provide further details.

The Revolutionary Armed Forces of Colombia, a much larger and potent fighting force, has been negotiating a peace deal with President Juan Manuel Santos' government for the past two years in Cuba.
