A vehicle packed with dynamite has exploded in the Colombian capital, shattering windows and damaging buildings. No injuries were reported.
The blast occurred Wednesday in Bogota outside the offices of a major Colombian television station. Officials blame the attack on leftist rebels of the Revolutionary Armed Forces of Colombia, known as the FARC.
The incident comes one day after suspected guerrillas detonated a remote-controlled car bomb as an army convoy traveled through the southern city of Florencia. The blast killed five civilians and one soldier. No one has claimed responsibility for either attack.
In a separate incident, nearly 30 soldiers are presumed dead in an explosion that occurred Tuesday after they stormed a house the rebels used to store dynamite. It is unclear whether the blast was accidental or intentional.
The developments come as the government negotiates a cease-fire agreement with the FARC, Colombia's largest and oldest rebel force.
In a related development, government negotiators met with the nation's second-largest rebel group, the National Liberation Army, for a second day in Cuba in a bid to revive stalled peace negotiations.
Cuban President Fidel Castro, diplomats and international observers attended the talks that are scheduled to conclude Thursday.
Colombia is in the midst of a 38-year civil war involving the rebels, right-wing para-militaries and government forces. The fighting has claimed at least 40,000 lives in the past decade alone.
