Interior Minister Alfredo Rada blamed what he called an organization of a terrorist nature for a dynamite attack Monday at the office building of a Bolivian trade union, COB, in La Paz.

No one was injured in the early morning explosion.

Two other attacks were reported in Santa Cruz - one at the house of a politician, and another at a hotel where President Evo Morales has stayed.

Rada called the attacks a challenge to Bolivia's democratic society.
