The Welsh victim of the EgyptAir crash was a "kind, loving" father-of-two who was "admired by many", his brother has told ITV News.
ITV News correspondent Rupert Evelyn reports:
Alastair Osman said his brother Richard, aged 40, had welcomed his new baby daughter into the world less than a month ago.
Richard had a home in Paris, he said, and also had a 14-month-old daughter with his wife Aurelie.
Aurelie was the one who raised the alarm when the news his flight had gone missing first broke.
Describing his brother as a "workaholic" and "health-conscious", Alastair added: "It's so tragic. I can't believe it."
Raised in Carmarthen, Wales, Richard Osman was the eldest of four children.
He worked in the gold-mining industry and was one of 66 people on the EgyptAir flight MS804 from Paris to Cairo when it came down in the Mediterranean.
The trip would have been one of his regular work-related visits, Alastair said, which he made at least once a month.
Alastair told ITV News his family were still holding out hope that the pilot may have been able to land safely on the water - but said as time went on, he was trying to prepare himself for all possibilities.
