MIAMI (AP) _ A pipe bomb blew out the door of an art museum that has been criticized in the Cuban community over the handling of works by artists considered pro- Castro, but there were no injuries, police said.

''It's a barbaric act to bomb a cultural center like the Cuban museum,'' museum vice president Ramon Cernuda said, adding that the bombing Tuesday was an attempt to intimidate directors of the Cuban Museum of Arts and Culture.

''This is what happens when demagoguery reigns in this city,'' he said.

Police said they were unsure whether the pipe bomb was connected to the controversy, but the bombing occurred about an hour after directors met to discuss a controversial exhibit planned for later this month.

''We have only that a pipe bomb was thrown through one of the Cuban museum windows by somebody on foot or in a car,'' said police spokesman Armando Villorin said. Damage was limited to the glass door and a section of plaster wall inside the museum.

The museum flap began when Cernuda included works by artists considered sympathetic to the Cuban government in an April 22 auction.

Cernuda was the target of numerous threatening phone calls and was asked by other museum officials to resign but he refused.
