Raul Castro meets with Colombian and FARC peace negotiators

Cuban President Raul Castro met with negotiators from Colombia's leftist FARC rebels and the Colombian government in Havana on Sunday as the two sides race to a March deadline to finalize a long-awaited peace deal.

Earlier this week, members from the rebel group cast doubt on whether the parties would be able to wrap up negations by the March 23 deadline they've set for themselves saying they were trying to "do the impossible" and that there are still "major stumbling blocks" yet to resolve.

The government and guerrillas of the Revolutionary Armed Forces of Colombia (FARC) have been negotiating in Cuba for three years to end Latin America's longest war, which has killed 220,000 and displaced millions since 1964.
