The worried family of a British citizen who has started a hunger strike in an Iranian prison says he is "desperate to live".
Anoosheh Ashoori has been behind bars for more than four years after being arbitrarily arrested while visiting Iran.
The 67-year-old yesterday started a hunger strike in Evin Prison - where fellow Brit Nazanin Zaghari-Ratcliffe has also previously been detained - in frustration over lack of progress.
