But international human rights organizations say the Cuban government is using the prosecutions to intimidate Cubans from daring to protest again.

"We found that prosecutors were constantly charging Cubans for exercising their basic rights such as the right to protest peacefully, the right to insult their president or the right to insult police officers, exercising the right of freedom of expression," said Juan Pappier, a senior Americas researcher at Human Rights Watch (HRW).

On Monday, HRW released a report on the protests that it says documents 155 cases of alleged abuse against people involved in last year's demonstrations, "including harassment, arbitrary detention, abuse-ridden prosecutions, beatings, and other cases of ill-treatment that in some cases constitute torture."

The organization also accused the Cuban government of further cracking down on civil liberties to prevent more protests from taking place.

Marta Perdomo said she encountered the tightening restrictions first-hand after she was invited to Europe in June to speak about her sons to human rights groups and lawmakers. When she reached the airport in Havana, officials there told her and another mother of an imprisoned protestor they would not be permitted to travel.

"They said I was 'regulated' and couldn't go," Perdomo said.
