They are accused of setting up cells to train members in handling weapons and the manufacture of explosives in preparation for attacks on UAE soil.

Like neighbouring Saudi Arabia, the UAE regards the Muslim Brotherhood, the party of ousted Egyptian president Mohamed Morsi, as a terrorist organisation.
In 2013, it sentenced 60 people to jail terms of between seven and 15 years for links to the Brotherhood in the first trial of its kind in the country.

The Emirates remains a key Western ally in the fight against ISIS, having last month established with US backing a centre to counter the terorist propaganda, AFP reports.
