Two mail bombs, post-marked from Spain, exploded in the homes of a Romanian dissident writer and a former interior minister, wounding the ex-minister and an explosives expert, police said yesterday.

The exiled Romanians, writer Paul Goma and former minister Nicolas Penscu, each received a package Tuesday containing two books by former Soviet premier Nikita Khrushchev, police said.

"I received a package, apparently postmarked from Spain," Goma told police. "I opened it and immediately, it seemed to me that there was something abnormal."

Goma said the pages looked used and inside the package there was a small rectangular device that looked like it was wired. "I closed the package and threw it into the bathroom."

Coma then called police, who arrived with a bomb-detonating specialist. Police said the device exploded shortly after as detonating expert touched it. The specialist received slight hand injuries.

Penescu's wife told authorites her husband was seriously injured in an identical attack and was in the hospital with face, hand and torso injuries. She said her husband left Romania 11 years ago after being "imprisoned by the communists for 17 years." He is a member of the National Romanian Council in Exile.

Goma said, "Since my exile in Paris three years ago, I have received numerous death threats in Romanian by mail or by Phone."
