Yazira de la Caridad, mother of two, said the explosion shook her home a block from the hotel: "The whole building moved. I thought it was an earthquake," she said. "I've still got my heart in my hand."

Mayiee Pérez said she had rushed to the scene after receiving a call from her husband, Daniel Serra, who works at a foreign exchange shop inside the hotel. She said he told her, "I am fine, I am fine. They got us out," but had been unable to reach him since.
