Dubai: A Saudi political prisoner and human rightsinfo-icon activist is facing the very real and very grim prospect of death by beheading. What for? Participating in protests, "chanting slogans hostile to the regime" and filming protests for social mediainfo-icon.

Israa al-Ghomgham was arrested and thrown into a prison cell in the desert kingdom where she has languished for almost three years.

During that time, the 29-year-old and her five co-accused, who face a raft of charges after taking part in peaceful anti-government protests, have been refused access to a lawyer.

This week, at Saudi Arabiainfo-icon's counter-terror courtinfo-icon in Riyadh where the group is due to stand trial, prosecutors called for a brutal punishment -- execution by beheading -- in a case that has outraged human rights groups worldwide.

Ms al-Ghomgham is now the first woman to ever face the death penalty for taking part in a protest.\

Human Rights Watch said Saudi Arabia's Specialised Criminal Court, which was set up in 2008 to try terrorism cases, had been increasingly used to prosecute peaceful dissidents and was notorious for its violations of fair trial standards.

Human Rights Watch says Ms al-Ghomgham's charges do not resemble recognisable crimes.

As well as being charged with participating in protests and filming them, she was accused of forgery for using the passport photo of another woman on her Facebookinfo-icon account and "providing moral support to rioters" -- which amounted to attending funerals of protesters killed during clashes with security forces.

The Public Prosecution called for the execution of five of the six based on the so called 'Islamic' law principle of ta'zir, in which the judge has discretion over the definition of what constitutes a crime as well as the sentence.

Samah Hadid, Amnesty Internationalinfo-icon's Middle Eastinfo-icon director of campaigns, described the method of execution as the "most appalling possible punishment" and said it set a dangerous precedent for other women currently locked up in Saudi jails for similar "crimes".

"We are urging the Saudi Arabian authorities to drop these plans immediately," Ms Hadid said. "Sentencing Israa al-Ghomgham to death would send a horrifying message that other activists could be targeted in the same way for their peaceful protest and human rights activism."

'POLITICALLY MOTIVATED' CHARGES

She said charges against Ms al-Ghomgham, including participating in and inciting protests, chanting slogans hostile to the regime and attempting to inflame public opinion, were "absurd and clearly politically motivated to silence dissent" in the country's oilinfo-icon-rich Eastern Province.

"Saudi Arabia is one of the worldinfo-icon's most prolific executioners and the world cannot continue to ignore the country's horrific human rights record," Ms Hadid said.

"We call on the international community to put pressure on the Saudi Arabian authorities to end the use of the death penalty, which continues to be employed in violation of international human rights law and standards, often after grossly unfair and politically motivated trials."

Ms al-Ghomgham and her husband Moussa al-Hashem were arrested during a raid on their home on December 6, 2015, for their part in political protests in the eastern Qatif province in the aftermath of the Arab Spring.

The activist had become well-known for taking part in political demonstrations in the Eastern Province and documenting them -- namely filming and uploading videos on social media platforms, a practice she had been actively involved in since 2011.\

Her main platform, according to Human Rights Watch, was calling for an end to the notoriously conservative country's "systematic discrimination" against Shiainfo-icon Muslims.

Sarah Leah Whitson, Middle East director at Human Rights Watch, said Ms al-Ghomgham and her co-accused had been held in pre-trial detention and without legal representation for over two years. Their next court date has been scheduled for October 28.

"Any execution is appalling, but seeking the death penalty for activists like Israa al-Ghomgham, who are not even accused of violent behaviour, is monstrous," she said.

"Every day, the Saudi monarchy's unrestrained despotism makes it harder for its public relations teams to spin the fairytale of 'reform' to allies and international businessinfo-icon."

CRACKDOWN ON ACTIVISTS

Human Rights Watch said a recent crackdown on women's rights activists had led to the arrest of at least 13 women under the pretext of maintaining national security. Some had since been released while others remain detained without charge and had been branded as "traitors" by the mediainfo-icon. They face up to 20 years in prison for their activism.

In May, Saudi blogger Eman al-Nafjan was detained along with six other women's rights activists and in early August. Amal al-Harbi -- the wife of jailed Saudi Civil and Political Rights Association founding member Fawzan al-Harbi -- was also detained. The reason for Ms al-Harbi's arrest is unknown.

This month, two more prominent female human rights activists Samar Badawi -- sister of jailed blogger Raif Badawi -- and Nassima al-Sada were arrested and thrown in jail, which according to Amnesty International, was "proof of a crackdown that shows no sign of relenting".

Amnesty International said the women had been "repeatedly targeted, harassed and placed under travelinfo-icon bans for their human rights activism" and called for their immediate and unconditional release.

"This unprecedented level of persecution of human rights defenders in Saudi Arabia is a disturbing sign that the crackdown is far from over," said Lynn Maalouf, Amnesty International's Middle East researchinfo-icon director.

"These brave women represented the last vestiges of the human rights community in the country and now they too have been detained. Saudi Arabia's new leadership under Crown Prince Mohammed bin Salman has crushed any spaceinfo-icon for the existence of human rights defenders in the country.

"Despite the Saudi authorities' repeated attempts to project the image of a country implementing sweeping reforms to 'modernise' the kingdom, the grim reality is of continuing arrests of activists for their peaceful human rights work," she said.

Saudi Arabia has a notoriously bad record on human rights -- particularly when it comes to certain nationalities, religious tolerance and the treatment of women.

"If the Crown Prince is truly serious about reform, he should immediately step in to ensure no activist is unjustly detained for his or her human rights work," Ms Whitson, of Human Rights Watch, said.

Lynn Maalouf, Amnesty International's Middle East research director, has called on the international community to step in and use diplomatic means to push for the activists' release.
