British couple held in Iran are on hunger strike, son says

A British couple jailed in Iran after being accused of espionage have gone on hunger strike in a "cry out for help", their son has told the BBC.

Craig and Lindsay Foreman were on an around-the-world motorbike trip when they were arrested by Iranian authorities in January.

Joe Bennett, Lindsay's son, described the charges against them as "ludicrous". He said his mother had told him "not eating was the only power she's got", in the seven-and-a-half minute phone call she was permitted on Tuesday.

"She said she felt lost and let down by the government here as well as the authorities in Iran," he added. The UK Foreign and Commonwealth Development Office has been approached for comment.
