Farc leader Ivan Marquez on peace talks with Colombia

The Colombian government and the left-wing rebel army, the Farc, have signed an agreement in the Cuban capital, Havana.

It marks a key step towards a final peace accord after five decades of conflict.

The deal tackles victim compensation - as well as how those responsible for the violence will be tried and punished.
