An Israeli court has sentenced Mordechai Vanunu to six more months behind bars after he violated a ban on speaking to foreigners.
In 2004, Vanunu completed an 18-year prison term for spilling nuclear secrets, and Israel has barred him from travelling abroad and monitored his movements since he left jail.
Israel alleges he has more details on the Dimona atomic reactor to divulge. Vanunu denies that but says he will pursue anti-nuclear activities.
"I don't want to live here. I have the right to be free," Vanunu (52), said after the sentencing at Jerusalem Magistrate's Court. "I want to be free and I want to leave."

The court, which also handed Vanunu a six-month suspended sentence, held off on jailing him to allow for appeals. Vanunu's lawyer, Michael Sfard, said he had until September 9th to decide on a course of action but hinted he might not fight the prison time.
"This is a cruel sentence in a case that has nothing to do with national security or social values. It's a measure of the vindictiveness of the state of Israel," Mr Sfard said.
"While Vanunu has perfect grounds for an appeal, we will have to give thought to whether that is what is wanted."
Vanunu was jailed on treason charges in 1986 after giving an unauthorised interview to a British newspaper about his work as a mid-level Dimona technician. The disclosures all but blew away the secrecy around an assumed Israeli atomic arsenal.
Since his release Vanunu has campaigned for Israel to be disarmed. He openly defied an order, issued by Israel's military
and upheld by the Supreme Court, that sought to curb his contacts with foreigners and international media.
"While returning a man to prison after he served 18 years there does not bring joy to anyone, there was no other choice but to take this step to make clear that the nation will defend its secrets and protect its security," prosecutor Dan Eldad said.
Israel neither confirms nor denies having the Middle East's only atomic weapons under a policy of "strategic ambiguity".
