Yailin Yanet Jiménez Alvelaes, sister of Ernesto Míchel Pérez Alvelaes, a young Cuban detained by the armed forces of Ukraine while fighting as a mercenary in the Russian army, made a heartfelt public appeal from the island to seek leniency and information about his situation.
The only thing we know about my brother is that he is detained as a mercenary in Ukraine. We don’t know if he is still alive, we don't know anything, said the young woman in statements shared by journalist Mario J. Pentón, who published the video on his YouTube channel along with the testimony of the detainee and an analysis of the case.
Jiménez assured that the family has not received any official information: “No one has reached out to us, no one has given us anything to know about my brother. We are completely desperate.”
He also appealed to the Ukrainian authorities: “to release him, at least deport him to Cuba, that is all we ask, to be given information, to let us speak with him for even five minutes, just to know that he is okay. That they do not mistreat him, that they do not do anything to him, please.”
The young woman explained that her brother, 26 years old and from Trinidad, Sancti Spíritus, left the country seeking to improve the family situation. “My brother's name is Ernesto Míchel Pérez Alvelaes, he is 26 years old, and my name is Yailin Yanet Jiménez Alvelaes. We are siblings on our mother's side. About six months ago, he went to Russia with the purpose of improving our lives, both his and his family's,” she said.
"Then, after spending five months there, he met some friends who told him about this work contract that was a war contract but not to fight anywhere, rather for building bunkers and those kinds of things. Where he went, he saw that it seemed to fit that work contract because they offered him a large sum of money,” he added.

Ernesto Míchel Pérez Alvelaes is one of the three Cuban citizens captured by Ukraine in the context of the war, alongside Turcas Yusbel González and Frank Darío Yarosse. So far, it is unclear what their legal situation will be or if they will face formal charges.
In the background of the case, it was reported that he was recruited on August 1 after arriving in Moscow with a construction contract. According to his own testimony, he was sent to the front after being deceived, and witnessed the deaths of at least ten fellow countrymen before surrendering to the Ukrainian forces.
Additionally, Ukrainian military intelligence (HUR) estimates that over 20,000 Cubans have been recruited by Russia, mostly with misleading promises of employment. More than a thousand signed contracts between June 2023 and February 2024, and many ended up on the front lines without military training or informed consent.
Cuban authorities have denied involvement in recruitment, but Ukrainian officials and U.S. congress members claim that the regime has facilitated or overlooked its existence, leading to calls for sanctions to be imposed.
Meanwhile, from Cuba, Ernesto Míchel's family holds onto hope: “All we ask is to know that he is alive, that he is being taken care of, and that, if possible, he is returned home,” his sister said.
