During a press conference in Cuba, an American attorney—in Cuba to defend a Cuban dissident—was arrested and jailed.

The Miami Herald reports:

An American human rights lawyer representing an imprisoned Cuban artist was arrested in Havana on Friday, according to the Human Rights Foundation.

Kimberley Motley was in the country to advocate for 33-year-old Danilo “El Sexto” Maldonado, a dissident artist jailed for posting a video on Facebook mocking Fidel Castro’s death. He was scheduled to attend Art Basel, but has been imprisoned without charges since Nov. 26, relatives said.

The foundation reported that Motley was led away by plainclothes security agents while she was holding a press conference outside Havana’s National Capitol around 4 p.m. Friday. Authorities also arrested dissident punk rock artist Gorki Águila and democracy activist Luis Alberto Mariño, according to the foundation.
