Israel has charged a former cabinet minister with spying for Iran, the Shin Bet internal security service says.
Gonen Segev, a medical doctor who served as energy minister in the 1990s, was allegedly recruited by Iranian intelligence while living in Nigeria.
He was detained during a visit to Equatorial Guinea in May and extradited following a request by Israeli police.
The 62 year old was jailed for five years in 2005 for smuggling drugs and forging a diplomatic passport.
He also had his medical licence revoked, but was allowed to work as a physician in Nigeria when he moved there after his release from prison in 2007.
