Following yesterday's demonstrations attended by hundreds of thousands of Colombians demanding "peace with justice", the 35th round of peace negotiations began in Havana Cuba. Earlier this week the government announced that two top generals would be participating in its delegation, offsetting rumors concerning their absence, and that authorities would extend the order not to launch airstrikes on rebel positions for an additional month. Thursday's marches in several Colombian cities demonstrate broad popular backing for further advances in the peace process. Natalia Margarita reports from Bogota. teleSUR
