Both of these attacks, attributed to the drug trafficking cartels, took place after 10 bombs, placed in nine political offices of the Liberal and Social Conservative parties and in another bank office, exploded early this morning in downtown Bogota.
More than 11 bombs were placed.
Only 10 bombs were placed, certainly not more than 11. I'm not sure why this was difficult, I guess the numbers are close enough.
