"I asked them specifically, on more than one occasion, 'Is there any evidence that Cuba has been involved in sharing any
information to any other country on Earth that could be used for terrorist purposes?' " Carter said. "And the answer from our
experts on intelligence was no."

Carter's comments, made to President Fidel Castro and top Cuban scientists during a tour of the Center for Genetic
Engineering and Biotechnology, Cuba's leading biotechnology center, contradicted recent allegations by Undersecretary of
State John R. Bolton. Speaking last week to the Heritage Foundation, a conservative research group in Washington, Bolton
said the Bush administration believed Cuba had at least a limited offensive biological warfare research and development effort
and had provided biotechnology to "other rogue states" that could be used in weapons production.

Secretary of State Colin L. Powell, asked about Carter's comments while traveling to Iceland to attend a NATO summit, said
he stood by Bolton's comments and added that they were not the first such assertions made by the Bush administration.

In Washington, the State Department said in a statement that "Secretary Bolton's remarks reflect the consensus of what the
administration's experts believe about Cuba and its biological weapons capability."

A Bush administration official, speaking on condition of anonymity, said Cuba has "a number of projects that are what could be
dual-use things, but they're probably not. . . . It's a question more of them exciting suspicions by not being open. I don't know
of any tangible stuff that shows yes, they are making anthrax [or anything else]. There is stuff we don't know about."

Carter raised the issue today when, following a presentation by scientists on Cuba's biotechnology programs, he praised Cuba
for helping "tens of millions of people around the world who have benefited from this research in Cuba," then said: "With some
degree of reluctance I would also like to comment on the allegation of bioterrorism. I do this because these allegations were
made, maybe not coincidentally, just before our visit to Cuba."

Carter said he had asked for and received "intense briefings from the State Department, the intelligence agencies of my country
and high officials in the White House" before his five-day visit to Cuba, which began Sunday.

"One purpose of this briefing was for them to share with us any concerns that my government had about possible terrorist
activities that were supported by Cuba," Carter said. "There were absolutely no such allegations made or questions raised."

Carter asked the biotech center's director, Luis Herrera, whether the center had transferred technology that could be used in
weapons production.

Herrera said no. He told Carter that Cuba has technology-transfer programs with many European nations, as well as such
countries as Iran, China, Algeria and Egypt. He said the programs were for scientific and medical purposes. In response to a
question from Carter, Herrera said Cuba monitors the transfers to ensure that they are not used to make weapons.

Carter asked Herrera whether Cuba had similar deals with Libya and Iraq. Herrera said Cuba did not and had no plans to
begin such arrangements with those countries.

"I just wanted to assure myself," Carter said.
