The Israeli former nuclear technician Mordechai Vanunu, released from jail in April after 18 years in jail, has been re-arrested, police sources say.
Vanunu was imprisoned for treason over his disclosures about Israel's nuclear weapons programme.

Police sources say he has been held on suspicion of passing on classified information.

Strict conditions were imposed on him after release, including a ban on giving interviews to foreign media.
