Since late 2011, the UAE has arrested and detained dozens of people it says are a threat to national security, most of them members of Jamiat Al-Islah wa Tawjih, an Islamist group with links to the Muslim Brotherhood. Al-Islah denies any wrongdoing, saying it is simply advocating a more participatory form of politics, and human rights groups have repeatedly condemned the crackdown on political activism. On 4 March, 94 people thought to be linked to Al-Islah went on trial, accused of attempting to seize power.
