Saudi Arabia has executed a young man over his reported involvement in anti-government protests when he was a teenager, human rights groups said Tuesday.

The Saudi Ministry of the Interior announced that Mustafa al-Darwish, 26, had been executed, according toReprieve.

Al-Darwish's family received no advance notice of his death and learned that he had been executed by reading the news online, Reprieve said.

Al-Darwish was arrested in May 2015 and charged with offenses related to his participation in protests -many of which occurred when he was 17 years old, according to Reprieve.

The non-profit organization said that al-Darwish was placed in solitary confinement and "beaten so badly that he lost consciousness several times."

"To make the torture stop, he confessed to the charges against him," Reprieve said.

Amnesty International,which had called for the execution to be halted last week, said al-Darwish was "the latest victim of Saudi Arabia's deeply flawed justice system which regularly sees people sentenced to death after grossly unfair trials based on confessions extracted through torture."
