Tatiana Posso joins the other 727 activists killed in Colombia since the country's peace agreement was signed in 2016.
Social leader Tatiana Paola Posso Espitia, 35, was shot twice in the head Wednesday morning in front of her house in El Copey located in the Department of Cesar when two men on motorcycles fired at the activist and fled the scene.
The assassination occurred just as Espitia's taxi driver, Wilson Ortega Palomino, arrived at her home to take the social leader to work, according to local media reports. The bad timing resulted in Ortega also being shot four times by the hitmen. He is in critical condition at a nearby hospital.
The National Network for Democracy and Peace in Colombia published a communique on its Twitter account firmly condemning the murder.
"Posso Espitia was a social activist committed to humanitarian aid, helping vulnerable people and victims of the armed conflict that continue to affect Colombia," said the report.
The organization added that the social activist, who was a candidate for the community council, was a beloved member of her community.
The document also explained how the city El Copey has had a long history marked by threats against social leaders, deaths and massive displacement of the population.
The tragic event comes as the Institute of Studies for Development and Peace (Indepaz) showed that since the signing of the peace agreement between the disarmed Revolutionary Armed Forces of Colombia (FARC) and the government of former president, Juan Manuel Santos in November 2016, 727 social leaders or human rights advocates have been killed in Colombia.
Colombia's Ombudsman announced Wednesday that at least 983 social leaders have been threatened with death in Colombia, 50 percent of them are women.
Last week, the 'We Defend Peace in Colombia' human rights organization called for major peaceful protests in the country and abroad meant to pressure the President Ivan Duque administration into fully addressing the rampant murders.
The global march is set to take place July 26 and is meant to "pay tribute to the (assassinated) social leaders and to demand action to end these crimes," said organizers.
