A senior Cuban official says that an American government contractor detained in Cuba for more than a month was "working for American intelligence."

Parliament leader Ricardo Alarcon says the man is under investigation but has not yet been charged.

Neither government has identified the man who was arrested on Dec. 4 on suspicion he was handing out communications equipment to opposition groups.

Alarcon says the man's actions are "part of the privatization of war."

The State Department has said that he was working a Maryland-based economic development organization. The company's president has said he was part of a U.S. government-financed program to "strengthen civil society" in Cuba.

Alarcon spoke on Wednesday.
