Palestinian Authority (PA) security forces have detained a human rights activist over a Facebook post on Monday.

It occurred after a journalist was arrested for calling on President Mahmoud Abbas to resign.

Issa Amro, a coordinator for the NGO Youth Against Settlements, questioned security forces on social media over the arrest of Ayman Qawasmi, a radio journalist who called on Abbas to resign for failing to protect Palestinians.

Amnesty International censured the arrest, describing it as a “shameless attack on freedom of expression.”

“Criticising the authorities should not be a criminal offence. Issa Amro’s arrest is the latest evidence that the Palestinian authorities are determined to continue with their repressive campaign against free speech,” said Magdalena Mughrabi, deputy director for the Middle East and North Africa at Amnesty International.

Amro had also urged spreading the news about Qawasmi’s arrest and reporting and documenting the authorities’ violations.

Ahmed Amro, Issa Amro’s brother, said security forces came to their house on Sunday evening looking for the activist and asked him to stop by “for a conversation”.

“He went to them on Monday morning, and until now we haven’t heard from him. We have no way of communicating with him,” Ahmed Amro said.

“My brother didn’t do anything wrong. We don’t know why they arrested him.”
