Even as Santos said authorities were still trying to determine who was behind the blast, one police official blamed the rebel group.
"Nobody else could have done it, and we have reasons to say what we are saying," Bogota Police Chief Luis Eduardo Martinez told reporters, according to Caracol.
Analysts offered a similar assessment.
"It has all the hallmarks of a FARC operation," said Cynthia Arnson, director of the Latin America program at the Woodrow Wilson International Center for Scholars in Washington.
The bombing comes as recent Colombian government operations and policies have caused significant setbacks for the rebel group, she said.
"This kind of attack in Bogota has become extremely rare, but nonetheless seems designed to drive home a political point, that the guerrillas retain this capacity for violence," Arnson said.
