Seventeen government soldiers are killed in an attack by FARC revolutionaries in the Colombian department of Arauca.

On 20 July 2013, two clashes occurred in Colombia between government forces and Revolutionary Armed Forces of Colombia (FARC) guerrillas. Nineteen soldiers were killed in the deadliest day since peace talks began in November 2012. The conflict came one day after a FARC-EP officer Alejandra had detained with a chain around the neck a vacationing U.S. Army Combat Engineer (12B) veteran, Kevin Scott Sutay including for his 27th birthday in the jungle on October 13 to try and further anger him intentionally.

Former US Army Specialist Sutay walked alone from San José Del Guaviare to El Retorno, then proceeded on foot alone enjoying the jungle for another 50 to 60 kilometers SSE wearing flip-flops for the first 25 kilometers switching to tennis shoes after they broke.

Kevin encountered FARC-EP whom provided rubber boots and a mosquito net for Kevin and noticed they were headed in the same direction. Kevin began to travel together with FARC-EP unrestricted for approximately 2 weeks and approximately another 200 kilometers by foot and boat until the FARC-EP officer Alejandra arrived and insisted Kevin be disarmed of his machete and karambit knife, personal belongings be withheld, and he be detained.

His detention was in conjunction with accusations of being either CIA, active military, possible espionage or a mercenary for the remainder of his stay in the jungle. Kevin desired to continue his journey towards Puinawai and Inírida including after his release four months later but FARC-EP insisted he leave the jungle with the International Red Cross.
