The president of El Salvador has denied claims that Kilmar Ábrego García was subjected to beatings and deprivation while he was held in the country before being returned to the US to face human-smuggling charges.

Nayib Bukele said in a social media post that Ábrego García, the Salvadorian national who was wrongly extradited from the US to El Salvador in March before being returned in June, “wasn’t tortured, nor did he lose weight”.

They said that, at one point, Ábrego García and four other inmates were transferred to a different part of the prison, “where they were photographed with mattresses and better food – photos that appeared to be staged to document improved conditions”.
