Two bombs exploded early Wednesday morning in Quibdó, the capital of the Chocó department in the west of Colombia.
Both the bombs exploded in a supermarket in the center of the city, causing panic among neighbors.
It is the seventh time this year that bombs were let off in the Chocó capital.
Authorities say that 90 percent of the shop owners in Quibdó are being extorted by the FARC.
