WASHINGTON - Cuba's Raul Castro has kept the system his brother Fidel used to repress critics, refusing to free scores of people imprisoned years ago and jailing others for dangerousness, Human Rights Watch said in a report issued on Wednesday.

The assessment came as President Barack Obama says he wants to recast ties with Cuba and Congress is considering lifting a ban on U.S. travel to the Communist-run island 90 miles from Florida.

Fidel Castro temporarily ceded power to his younger brother Raul in July, 2006 and formally stepped aside as president last year because of illness.

Raul Castro has relied in particular on a Cuban law that lets the state imprison people even before they commit a crime, Human Rights Watch said.

The group documented more than 40 cases under Raul Castro in which Cuba has imprisoned individuals for dangerousness because they sought to do things such as stage peaceful marches or organize independent labor unions.

In addition, 53 prisoners who were sentenced in a 2003 crackdown on dissidents under Fidel Castro are still in jail, the report by the global human rights monitor said.

Systematic repression has created a climate of fear among Cuban dissidents, and prison conditions are inhumane, said Human Rights Watch, whose researchers traveled to the island for two weeks during the summer for their report.

Jail is only one of the tactics used, it said. Dissidents who try to express their views are often beaten, arbitrarily arrested, and subjected to public acts of repudiation.

In one recent well-publicized example, Cuban dissident blogger Yoani Sanchez said she was beaten this month by men she thinks were state security agents.

The independent Cuban Commission on Human Rights estimated this year that Cuba has 200 political prisoners. It says the government now favors brief detentions over long sentences because they intimidate without hurting Cuba's image abroad.


In Congress, a key Democrat said the report showed the need to lift the U.S. travel ban on Cuba. That would be the best anti-Castro-policy, House Foreign Affairs Committee Chairman Howard Berman told Reuters.

Americans visiting Cuba would be ambassadors of democratic values, thus undermining the Castro government, he said.

I think the Castro regime likes our current policy. They are very nervous about us opening up travel to Cuba, Berman said. He is holding a hearing on the travel ban on Thursday.

But Florida Republican Rep. Lincoln Diaz-Balart, a Cuban-American who was born in Havana, said it was important to retain the travel ban. U.S. tourists flooding to Cuba could mean billions of dollars for the (Castro) regime, he said.

The United States has restricted trade and travel with Cuba since the 1960s in what started as a Cold War policy to isolate Fidel Castro after his 1959 revolution. But the U.S. embargo has lost international support, with only Israel and Palau backing the U.S. policy at the United Nations this year.

Since taking office in January, Obama has taken steps to ease the embargo as well as reopen dialogue with Havana.

But he also has called on its government to reciprocate by freeing detained dissidents and improving human rights.

Human Rights Watch favors an end to the U.S. travel ban. It says Washington should also end its failed embargo policy that has won sympathy for the Castro government abroad.

But before lifting the embargo the United States should agree with allies in Europe and Latin America to jointly demand the immediate release of Cuban political prisoners, it said.

If Havana does not respond in six months, countries should impose joint punitive measures on Cuba, the report said.
