Amnesty urges Yemen rebels to free journalists facing death penalty
The four, Abdul Khaleq Amran, Tawfiq al-Mansouri, Harith Hamid and Akram al-Walidi were arrested in June 2015 in Yemen's rebel-held capital Sanaa.
"Yemen's Houthi de facto authorities must quash the death sentences and order the immediate release of four Yemeni journalists who are facing execution following a grossly unfair trial," the rights group said in a statement on Friday.
The Iran-backed Houthis seized Sanaa from the internationally recognised government in 2014, prompting the intervention of a Saudi-led military coalition to support the government.
In April 2020, a Houthi court sentenced the four journalists to death on charges of "treason and spying for foreign states".
"This has been a sham of a trial since the beginning and has borne a terrible toll on the men and their families," said Amnesty's Middle East and North Africa deputy director Lynn Maalouf, according to the statement.
One of the detained men, Mansouri, is in a "critical health condition" with heart and other ailments, Amnesty said.
"Pending their overdue release, the journalists must be provided with urgent medical care -- the denial of medical treatment for the seriously ill is an act of cruelty which amounts to torture and other ill-treatment," the statement said.
At the time of their trial, Amnesty criticised their sentencing on "trumped-up charges", while Reporters Without Borders called the verdict "totally unacceptable".
Their arrest was motivated by their reporting on "human rights violations committed by Houthi forces," the International Federation of Journalists and the Yemeni Journalists' Syndicate have said.
An appeal will be heard by the Specialised Criminal Appeals Division in Sanaa on Sunday.
Hundreds of thousands of Yemenis have lost their lives and millions been displaced during the war, in what the United Nations has called the world's worst humanitarian crisis.
