Israeli security officials say they re-arrested nuclear-whistle blower Mordechai Vanunu early Thursday.
Officials say Vanunu is suspected of giving unauthorized information to foreigners.
He was set free in April, after serving 18 years in prison for divulging classified information about Israel's nuclear program to the London Sunday Times.
Under conditions of his release, Vanunu is still barred from leaving the country or discussing Israel's nuclear program. His contacts with foreigners also are restricted.
