A human rights activist in the United Arab Emirates (UAE) says three members of a religious society linked to the Muslim Brotherhood have been arrested.
The UAE has come down hard on the al-Islah society over the past year.
On 2 July, 68 people, most of them al-Islah members, were convicted of a plot to overthrow the government.
Human rights groups said the trial judge had failed to investigate "credible" allegations of torture of the defendants.
The new arrests have all occurred within the last week.
