People hold Colombian flags after a mass in honour of 11 provincial politicians who were killed while being held hostage by the Revolutionary Armed Forces of Colombia, or FARC, in Lima July 5, 2007. Hundreds of thousands of Colombians headed for the streets on Thursday to show outrage at last week's news of the deaths. FARC said last week the 11 provincial politicians held for more than five years had been killed in a cross fire when an unidentified military group attacked their secret jungle prison. But President Alvaro Uribe says state security forces were nowhere near the camp and accuses the rebels of murdering the men, in an incident that has shocked the country.
