In February, a South African judge

Mr Berman said his 27-year-old brothers were "at risk every single day"."We know they are alive. The released hostages saw them."

He said he believed Gali and Ziv had been injured when they were seized but that he worried their mental condition was "not good" after so long in captivity.With the release of emaciated and frail hostages in February, Mr Berman said he was worried about his brothers' conditions."We need to pressure Hamas and its enablers."

For 491 days, Or Levy was held by Hamas not knowing whether his wife Einav had survived the 7 October attack on the Nova music festival where he was taken.She didn't and for more than a year his three-year-old son Almog was without both his parents. In February, Or, weak and painfully thin, was released by Hamas.

His brother, Michael Levy, told BBC News he was worried about the impact on the hostages if Israel sent more troops into Gaza.

"I'm concerned it will affect the hostages, that the terrorists can decide to do something to them," he said. "I do believe the army knows what it's doing and they will make sure the hostages aren't affected, but it's always a concern."But Sian's staying optimistic.

"I don't want to jinx it, but it has been sunny every single year," she says."So bring sun cream, bring hats."

Some wellies might be a good shout, too."Look after yourself. Keep an eye on each other. Get some water going. Just be sensible and have a good time," says Sian.
