HAVANA, May 16 (Xinhua) -- Colombia's two guerrilla groups, the Revolutionary Armed Forces of Colombia (FARC) and the National Liberation Army (ELN), have decreed a unilateral eight-day ceasefire to coincide with the May 25 presidential elections, a rebel spokesman announced Friday.
"We order all our units to cease any offensive military action against state armed forces or economic infrastructure, from 00:00 hours on Tuesday, May 20, to 24:00 on Wednesday, May 28," said FARC spokesman Ivan Marquez in Havana, Cuba, where FARC and Colombian government officials are negotiating a peace deal.
Marquez described the gesture as a "beacon of hope" for a bilateral ceasefire, and an initiative that responds to a popular demand "that deserves to be heard."
The statement, read to reporters before delegates resumed their daily negotiations behind closed doors, was signed by the leaders of both guerrilla groups.
This is the third unilateral truce announced by the FARC since peace talks began in November 2012 to end a half century of armed conflict, and the first time both rebel armies have proposed a joint unilateral ceasefire.
The ELN is also looking to enter into peace talks with the government.
The government delegation in Havana, led by Humberto de la Calle, refused to comment on the guerrillas' announcement.
Colombian President Juan Manuel Santos is running for re- election on a platform that includes brokering peace with the rebels.
