The targets were tourist hotels.  One was the Hotel Melia Cohiba in Havana.  It is considered Cuba's finest hotel and is popular among wealthy tourists.  No one was injured in any of the bombings.

It is currently unknown who set the bombs off.  A wide range of suspects were offered by people interested in the matter.  Some suspected that anti-Castro groups were behind the attacks, others thought it may be one person acting alone.

The United States Government and some others even claimed that the Cuban police may have planted the bombs so they would have an excuse to increase measures against dissention.
