An Abu Dhabi court has sentenced 30 people to up to five years in prison on national security charges.

Twenty Egyptians and 10 UAE citizens were sentenced by the UAE Federal Supreme Court for stealing and distributing confidential information from the Supreme Council for National Security (SCNS).

Prosecutors alleged the group was linked to an Emirati Islamist society known as Al-Islah, which they said was an international branch of the Muslim Brotherhood.

The court’s judge also ordered the closure of “all branches of the Brotherhood in the country” and the seizure of “all funds and properties” related to it.

Six of the 20 Egyptians were tried in absentia.

The 10 Emiratis had previously been convicted in July, along with 59 others of attempting to overthrow the country’s political system. They were all sentenced to prison terms of up to 10 years.

Human rights group, Amnesty International said in a statement before the sentencing that it considers three of the convicted men to be prisoners of conscience who were imprisoned solely for exercising their right to freedom of expression and association. These are Mohammed al-Mansoori, a lawyer, Hussain Ali Alhammadi, a physicist and Saleh Mohammed al-Dhufairi, a former teacher.

The group also alleges numerous irregularities in the case, along with allegations of torture and ill-treatment.
