After five decades of armed conflict, Colombia has the highest number of internally displaced people (IDPs) in the world after Syria.
United Nations figures suggest 5.7 million people have been displaced by the conflict between left-wing rebel groups, right-wing paramilitaries and the armed forces.
A couple of hundred displaced people recently set up camp in Plaza Bolivar, the main square in the capital, Bogota, to draw attention to their plight.
Photographer Viviana Peretti documented their protest.
An estimated 40% of displaced people are children and NGOs say displacement is creating a lost generation which has little access to education and health services.
Colombia is one of the world's most heavily mined countries, and many of the displaced have had limbs amputated.
The landmines are placed by the rebels and also drug traffickers with the aim of protecting their crops from eradication by the security forces.
Many of the displaced were driven from their homes decades ago and are demanding more help from the state.
Some of them are asking for financial compensation from the authorities, while others want help finding a new home.
Most had to leave their homes with only the things they could carry and have not dared return while the conflict continues.
While the government is holding peace talks with the country's two main rebel groups, it has refused to call a ceasefire, meaning that armed clashes continue to displace thousands.
In the meantime, the displaced are praying for a resolution to their precarious situation.
