"The United Arab Emirates said on Sunday it has dismantled a group plotting against state security without identifying their affiliation or the number of arrests.  The prosecutor general, Salem Said Kabish, said an unspecified number of people were being questioned for having formed "a group aimed at damaging the security of the state," the official news agency WAM reported.  It said they were also suspected of "rejecting the constitution and the founding principles of power in the Emirates" and of having links with foreign organisations."
